Since my mom isn't mom enough to help me, can someone please help me??

Ok...long story short. When I was like in 7th grade, I went to see a psychologist because I wasn't getting along with my mom. They said I had depression and add and gave me medication. I didn't take the medication, and was ashamed to go to counseling so I quit both. Fast forward another 3-4 years later, and now I have alot of social problems. I KNOW for a fact I have avoidant personality disorder...it's just something I know I have. I have researched the symptoms for about 6th months, and I just know I have it. My mom WON'T take me to the psychologist and psychatrist again because she think's I won't take my medication. She thinks I act normal. She has NEVER seen me interact with anyone...and when she does she says I seem nervous but nothing more. She just doesn't know. I'm such a loner. I admit that I need help before it gets worse. HOW CAN I GET MY OWN HELP AND GO TO A PSYCHOLOGIST ALONE?? How do I apply for psychiatric help??? I just dont' wnat to feel this way anymore. I'm trap
