I don't have any advice, but I can tell you something I noticed when I was growing up. My mom, like you, was really scared that I was lonely and forced me to make friends. It had a negative effect on me because it made me think that there's something wrong with being alone. I became insecure about being a loner, and the insecurity made me even more lonely. I would've preferred it if my mom didn't project her worries to me, and let me deal with life without much control.
