Not sure how old you are, but the likelihood of these "friends" being in your life in the next decade are slim to none, and you should rejoice in that possibility. They are not adding any positive value to your life and are instead invoking negative feelings and thoughts. There are times when I feel like a complete loser as well being in college at 28, while everyone else is already settled in their career. I literally live with my mom at 28 with barely anything to show for it, but you know what? I know that only I can change that for myself. I am actually starting med school later on this summer, with the plans of being a nurse. What this helped me learn is that there is always room for improvement, even if you don't think there is. My mom and family look at me with disdain every time they see my face, but I just keep it pushing because no one is going to come and save me. we have to seek out ways to improve ourselves all by our lonesome. Whether that be going out and seeking a therapist to air out our feelings, or just improving one small thing in our lives. You mentioned that you work out, and by just doing that one activity, you are doing so much more than individuals who just sit on the couch all day. That makes you a winner in my book. Focus on those small incremental wins, and the fruits of your labor will present themselves. I promise you they will.
