Problem unknown. Plz help. Skills?

Hello doctor, my problems: fear at night(no delutions, hallucination), very low self esteem, social anxiety, mental pain while I have been seen by others, embarrassment in public, laziness, poor communication skills, don't know how to speak to others, negative thoughts, feel like others are laughing at me, no friends, don't know how to make friends, extreme fear while speaking to people, feel like I'm not muscular enough, feel like I'm an useless guy, good for nothing guy, I have a forgettable past, pain all over my body, extreme asthma, poor body structure, unreasonable fear, financial problems, torn acl, etc... I'm under medications for the past 5 years for schizophrenia. I don't believe that I have schizophrenia. I feel I have some kind of personality disorder. Now I need to change doctor. Whom should I consult? A psychiatrist or a psychologist? Where should I learn all these basic things? How to think positive? Where to learn personality development skills? Help me. Thank you.
