I just feel like I dont have friends anymore?

I am 21 yr old male and I just see life around me is getting dull, boring and I feel like I am getting further secluded from the rest of society- both physically and emotionally. I just dont know where to go or who to talk to. I do have a small family, I trust them but it is not enough to satisfy my level of self confidence or anything similar. I have spoken to them about my troubles but it hasnt worked on addition speaking with a physcologist. I dont see my friends much, sometimes I dont like to hassle them because they are busy and have their own lives. I am just asking whether many people around my age experience this kind of situation of loneliness.
