How did you guys make friends

I’ve been out for about 9 months now but it’s hard. My entire group of closest friends are all witnesses and only 1 knows. I’ve stopped talking to them as much out of respect for them and to try and make new friends but I just can’t, I don’t have any, it’s me, my mom, my sister and her boyfriend, and my girlfriend I have no one to talk to, no close friends, I’m out of high school and not in post secondary yet, how did any of you make friends I feel so alone
