I feel like giving up on trying to date or make friends

I feel like giving up on trying to date or make friends So I (M20) Just seem to have a 0 luck and never get respect when I try to meet new people/make friends/date. It's starting to have an effect on me mentally and I just feel like sort of giving up and isolating. The past couple of years, I had been isolated and have been trying to get better the past 2 years. My stuttering is literally my cryptonite in everything that I try to do. I have literally met people in public where I will stutter and they will legitimately mock me in front of others and nobody helps, helps defend me, I just can't argue back or anything. Other times people just do not know what a stutter is and sometimes I'm not even mad, but what gets me aggravated is some people will talk to me like I'm special needs or like a baby and it really doesn't feel good. This has happened to me since literally school where teachers would do the same thing. I have some friends that do try to help me make friends and and I'm very appreciative and thankful for them but it feels horrible not being able to do stuff on my own without either getting made fun of or getting patronized.
