up until late last year i was like that for most of my life. almost shut in, going out excruciating.
i’m a vulnerable adult and was a vulnerable child, sexual trauma, becoming an adolescent and adult was pretty distressing to me. concept of being looked at sexually and/or expected/perused sexually from either sex was enough to make me reprogram my entire life. wasn’t just scared of predatory men but any romantic or sexual interest from anyone. when you’re a kid it’s pedos you’re scared of but as a traumatised adult it’s everyone capable of sexual interest.
i don’t know if i was ever acutely aware of that actually happening to me but experience or lack thereof aside, the idea was scary enough because of the sexual trauma.
nowerdays i have more of a handle on it and regularly leave the house, and dress in a way that doesn’t obscure my age and stuff. still get anxious going out but it’s much better than it was, still have heaps to process trauma wise in therapy and all the rest of it, and on bad weeks i get the urge to start hiding again, but it really can get so much better. it’s a fear that sticks with you but the control it has can heal.
not saying people don’t look and it’s all in your head (though i know the feeling of villainising everyone and everything), but it can start to feel not catastrophically threatening.
for obvious reasons my experience of this is probably different to yours, and i’m sorry you get stared at, it sucks but i think it can get less debilitating for anyone, eventually
