how do you not talk to the opposite sex when thats whom youre surrounded by

i go to this place (i cannot not go to this place, its like anecessity that i go there) but 99% of the people there are men, there are only a couple of girls. and we have groups. the group I am in has only boys in it. I dont talk to them. they talk to me they act dismissive when i say i dont want to talk to them. they peer pressure me into talking to them. all of them are autistic wallahi. I cant even. but talking to men is haram how do i not talk to them. Lmao and my parents they dont even take stuff seriously (i am a revert theyre not) anyways and just dont take situations like this seriously. theyre the reason i even go to this place.
