I Need Help

Hello fellow mangago readers and sorry to bug you with this question but does anyone have any tips to overcome my fear of public speaking? A few days ago, i had to do a speech in front of the class for a test and i totally bombed it. I was fine in the beginning but then my hands started trembling like crazy. I blacked out and missed some sentences. Then, in an attempt to rectify it, i made even more mistakes and said things that did not make sense. My pupils started to move in all directions and i tried really hard to focus on my flashcards. I finally managed to do it but after that i never lifted my head to make eye contact again. At one point, my voice just stopped and i had to take a few breaths to continue. I feel like crying so bad. I can't even ask my friends or family because they never have such problems and can become friends with literal strangers. I have already searched it on google multiple times before but i really want to learn from actual people. So, i appreciate any help i could get.

I could barely remember how the storyline was explained, nevertheless here are the few things and event's I remember from it ;

Note : Apologies in advance for I am not fluent with English, you may encounter some grammatical error throughout my explanation

A man is in a coma and his soul wanders the world. He is unaware that he is in a coma and assumes he is dead. During his wandering, he encounters a man (the bottom) who initially seems frightened. Over time, they develop a connection. One day, the man in the coma (the top) wakes up in the hospital. The bottom, believing the top has moved on to another existence, is distressed. The bottom has a confrontation with another person (a potential friend or suitor) in front of his apartment ( they were originally drinking at first, and then the guy or the suitor jumped on him taking advantage ). During this confrontation, the bottom is involved in an argument and is physically engaged with this person, which results in a band-aid on his chest becoming dislodged. The top, now awake, he goes straight to the bottoms apartment as he still recalls where it's from, now he sees the bottom with the other person and becomes upset. He intervenes, pushing the other person away and taking the bottom back to his apartment. Upon lifting the bottom’s shirt, the top notices that another band-aid is missing, leading him to suspect infidelity or something amiss in their relationship.
