I feel tired feeling like the only autistic person who has trouble making friends

I basically never had a friend during my childhood, even tho people claim it is "easier" to make friends then. Nowadays I know so many autistic people who have long term friends that they can trust. I try to make new friends constantly but it only ends with ghosting or people not giving the same effort back. And the friendships I currently have are always either temporary or fake, but I choose to be with the people just for not being lonely. Even irl support groups led by psychologists gave me weird stares when I expressed not being able to make friends, because according to everyone the only issue that should come with autism is not knowing when to message your already existing friends. It reached a point where I feel bitter about people who have large friend groups but say "I think I might be autistic", or the type of autistic people who say "I have no issue making friends, just keeping them!" and "I have no friends besides my one best friend I knew forever!"
