What to do with ed

I'm that 21 year old boy who had ed and wanted to suicide. Tnx for ur kind replies! Well i relapsed and went numb again till today that i came to a new realization about my problem. I can still get and maintain erection when sleeping on my back but it's not like before we can say 70% and when standing it's worse and i can't feel my scrotum at all but maybe still would be able to penetrate for 5 seconds and come. So my problem for now is that i feel so insecure and worried to get into a relationship. What if she breakes up bcoz of my ed?! And how can i feel confident in college when i suck at this? I always refuse gatherings after class as they all have their gf and i fu*king don't. I would be so glad if anyone could give me any advice on ed supplements, cockrings and penile prosthesis(satisfaction). Also i'm gonna move to live with my father and it's making me even more nervous as he always brags about having sex and shit and it goes on my nerves! I feel so incomplete and imperfect! Unworthy of everything in life! Even life itself! My dick is paralyzed.

 

I used to also feel an erection in my scrotum wich made my main erection stronger but now my scrotum is just flaccid and sensation of my dick is like 70% of what it used to be.
