I don't feel like i can go on, I'm so down, please help :(?

4 months ago i did stuff with my ex bf (fingering, oral sex and he placed his penis inside me) 2 days later he dumped me, hes slept with 4 people and after a few weeks my vagina started to swell up and i got heavy discharge, i have a few small lumps that flare up and down, i went to the docs and she said i don't have any stds but im not convinced she gave me thrush cream but my symptoms have gone, it seems worse, my urine smells and its itchy at times, my inner lips have got bigger and i have like little valleys either side of my clit :( I think i have herpes or aids, and i know for definite if this is the case then suicide will be deffinate i dont want to live if i have that, not being able to get a bf or have kids and dying! Also i have increased chest hair on my stomach and chest and boobs, i have severe bacne which im on tabs for but it has left me with disgusting scares, my last problem is my breasts, they never developed properly im tiny and they droop real bad and are pointy and my left boob is considerally bigger than my right, i told my mum im only 16 but i cant tell her about my vaginal problems, she thinks i just had thrush but i dont think i do, please help i cant take this anymore, i just want to die! i dont want to die but with all these problems i do, people think im so happy and confident but i have all these nasty secrets no one can never know, only you know the whole story :'( xx
