I have a friend that is very well-educated in mental diseases, and he says i show symptoms of anxiety. should i seek help? does medication even work?

Talk to a therapist: I would talk to a social worker, therapist, psychoanalyst, psychologist or psychiatrist about these suggested symptoms although it is important to remember it is your life too and something is only a problem for you if it gets in the way of you accomplishing your dreams! sometimes it helps to walk with a trained and objective third party and to see if there is a diagnosable condition. Stay safe!
