like 13 or so.
Puberty wasn't kind to me.
I grew full on, actually made of breast tissue, man tits due to hormonal bullshit despite not being all that fat.
Dad insisted that if I just worked out hard enough they would go away despite what the doctor said. So I did.
Even got the point of having visable abs and doing around a thousand push-ups a day. Still had ugly disgusting man tits.
Also my skin got significantly worse around that time so always had painful rashes somewhere or another.
Also scalp ezama or whatever caused anywhere I grew hair to have absurdly bad dandruff.
While the rashes eventually calmed down a bit, and I found a prescription ointment that works when it does flair up. The man tits and dandruff are still issues.
I manage the dandruff by washing my hair with anti-dandruff shampoos, rotating out the active ingredient once a week, and washing hair every other day. This mostly manages it.

Nothing can be done for the man tits though. The surgery cost tens of thousands of dollars.

So I am basically stuck being disgustingly ugly unless I somehow strike it rich, which realistically ain't happening.
I have already given up and accept that I will be single forever. Honestly isn't too bad once you actually accept it. There is lots to life besides relationships and building a family.
