Hopelessly Lonely

I'm 24 year old working male. I'm hopelessly lonely. I've always had a few friends in school but never deepened any relationship to talk a lot when we graduated. I went to the workforce while most my friends went to medicine. I feel isolated and alone. My current work is not even what I studied for plus I have ADHD and phone addiction so I can't even do good there. Nothing I have interest on ever gets me anywhere. I like something, do it for a while get bored and feel like I just wasted my time, thus I never feel any drive to improve myself anymore even on things that interest me. I always let people down in my work. I eat alone, no friends, working a job I donct think was meant for me and how I think. I feel like an imposter, disconnected and feel like even if I die no one would really care after a few months. I'd always listen to Dr. K, know what I need to do, but years of trauma prevents me to do anything. I'm not really sure what to do and am here to get support tips and maybe have some people to talk about this to.
