I wonder if anyone here works as a sales representative, specifically medical representative? I'm kinda depressed thinking about my future. I finished my pharmacy degree and started a office job (pharmacovigilance) which I didn't like and I had to quit within 3 months. Another option is medical rep. Where I can earn good money, but I'm scared. Somedays I feel like I can go talk to doctors and chemists but somedays I think oh shit how am I going to talk to doctors and stuff. Help me out.
