Everything seems to keep going down hill

I've been on low point for quite a while and everytime I think it starts to get a little bit better shit hits the fan and I'm back where I started. It feels like I'll never be able to reach the finishline. At this point it's not like I rationally don't know what to do but emotionally it's getting harder. I can talk to friends and family but it doesn't relieve me in any way at the moment. Anyone any experience with this kind off thing because I really need some encouragement on what to do next or if I can just wait this out or something...
