Needing advice on ritalin..?

Ever since I was a young boy I have always had aggression, attention, hyperactivity and depression problems. When I was 14 I started down the road of prescription medications. I was placed on several ssri's and a snri. They all seemed to make my problems worse. I kept trying med after med until I was placed on ritalin. The very first day I took ritalin I knew it was what I had been looking for. It took away my aggression, calmed me down, and helped me focus which in turn took away the depression I was feeling. I was 17 when I was put on ritalin but by then had developed a drinking problem. I am now 20 and at a rehabilitation center getting clean from the drinking. My mom called me last night and wants me off the ritalin. She said she wants me to be clean from everything and said that I was doing better since going to rehab and she didnt want me on the ritalin anymore. My addiction councellor has my mom thinking that the ritalin is of no benefit to me and if I wanted to get clean I needed to drop the ritalin. I know that alot of people are anti-ritalin but if you were in my shoes and couldnt sit still, work with others, and were depressed because you couldnt focus and felt like your mind was in a cloud then you'd rethink taking me off the ritalin. Ritalin helps me focus during the day and keeps me from falling behind not just in school but in my social life. Do you think that I should be off the ritalin after trying soooo many other meds with no success? I dont abuse my ritalin and the benefits it provides for me are unbelievable. Why ado they want me off the ritalin so badly if its what helps me live my life and stay on track. They had no problem throwing zoloft, effexor, clonazepam and other junk like seroquel at me but they dont want me on ritalin. any advice or opinions are greatly appreciated. thanks
