Have you read http://www.mangago.zone/read-manga/brother_x_brother/ ? Maybe it's not EXACTLY what you requested, but there's tragic past, trauma and seme that works hard to help his uke (it's also quite long, with nice developement and plot!)

This is nice too http://www.mangago.zone/read-manga/hatsukoi_wa_gunjou_ni_tokeru/
You can also try these, but only if you won't find anything better xD (I don't mean they're not good, but may not satisfy all your needs; I focused on trauma/tragic past)

http://www.mangago.zone/read-manga/hatsukoi_wa_gunjou_ni_tokeru/ ? hopefully this would be good!!! i enjoyed this one a lot ;-; you might have read this already though.....
the funny thing is I was kinda thinking I might have gotten sick or something because of my sleep deprivation but I (no joke) see the pictures move like a short second when I read something in the top right I can see slightly moving mouth or something below the page I was like what? is this gif or something? when I check it nothing happens thats how much I dont sleep LOOL (⊙…⊙ ) but it only happens when I don't sleep for more then 24 hours and the lights are dimmed
yeaah I totally get you this happens alot with me.
Im actually someone who functions better when I stay awake .but once Im in bed I don't remember when I fell asleep.
im like oh its 2:12 I should probably go to sleep by 2:30 ....shit its 3:45 ok at 4 ....then omg its 6 never mind I'll go when I go XD and then it takes me to the day after and I tell myself ...ok I'll sleep early tonight and then the whole cycle begins untill nothing is left
Same! I always tell myself "oh, I gotta sleep early today" etc. then of course I don't. I'm also insomniac, so even if I go to bed I may not sleep, just lay and stress out. So why bother.
I also get what you say about functioning better without sleep, sometimes I'm so full of energy and excited, my blood pressure rises and I can do a lot, so I want to continue for as long as possible until I'm almost dead xD
Hey. I really recommend this manga - http://www.mangago.zone/read-manga/new_york_new_york/ There are almost everything. In the beginning seme is stupid and bad, but don't stop reading, because there is a lot more after it.
Also, i think this mangas contains some things you want:
http://www.mangago.zone/read-manga/love_mode/ - loved it, its maybe not exactly what you are looking for, but there is rape (i do not count one in 1st chapter)
http://www.mangago.zone/read-manga/gekai_no_okiniiri/
http://www.mangago.zone/read-manga/kimi_no_naka_de_nemurasete/
http://www.mangago.zone/read-manga/senya_ichiya_shitone_no_himegoto/ - not rape, but a lot of mental problems and trauma
http://www.mangago.zone/read-manga/tsumaranai_otoko/ - ch. 3
http://www.mangago.zone/read-manga/hana_to_ryuu/ - i loved it
http://www.mangago.zone/read-manga/love_home/ - don't treally remember, but i think it is somthing like you are looking for
http://www.mangago.zone/read-manga/kimi_no_naka_de_nemurasete/ - also like above
Maybe this http://www.mangago.zone/read-manga/nichijousahan_bi_beautiful_life/ and this http://www.mangago.zone/read-manga/kinjirareta_taion/ and this http://www.mangago.zone/read-manga/takumi_kun_series/
http://www.mangago.zone/read-manga/makkurayami_de_kimi_to/ - uke scared of darkness
http://www.mangago.zone/read-manga/dog_style/
http://www.mangago.zone/read-manga/mezase_hero/ - rauma after rape. A lot more in vol. 2
I do not know if everything will suit your taste, bust you can check it out.
Okay, i have a list of rape, attempt of rape, trauma, abused ukes etc. Some are not like you are looking for, but there ale a lot that contains some things you mentioned so you can check it. I really do not remember exactly what manga contains what, but you can ask me any time you want. It may cantains spoilers.

where the uke was raped once before (not by seme) and he gets traumatized
and the seme helps him by being gentle ofcours not right immediately he tries multiple times but if the uke says STOP then he actually stops
not the type of he gets raped and shit im late for my lesson in school and he forgets all about it a realistic one preferred
with moments like whenever the uke gets touched he thinks of the "bastard" and then the seme goes like "well I make u feel real good that you don't remember the bastard but me instead" or I'll clean where he dirtied you type of thing
also they don't need to ONLY show love with sex but even have naked hugs or kisses or just actually sleep together without the banging
(writing this made me feel so perverted lol)
or any other manga where the seme is trying to force himself but stops when he sees the uke cry he stops and hugs him and ask for forgiveness
I would also love to see one like "cut" or "Ten Count" (like not liking to be touched and the seme works hard for him)
I rather see one that has completed or more then oneshot I don't like to read a short manga that ends too soon
im a sucker for traumatized uke's or sad ukes with phobias (any type of phobia) that find happiness with the seme but it has to be revolved around the phobia not just a One time mention of it
oh and happy ending is a must or an open ending where you can at least imagine them getting together and if they die or something they have to both die together in eachothers arms not one left behind
I've been looking for a long time and even the lists don't show what im looking for
sorry for the long question
