I've Been On Effexor For 10 Years For Menopause And

I've been on effexor for 10 Years for menopause and tiredness like depression 37.50, few years ago 75mg. Elavil for 26 for sleep problem and once in a while zopiclone. I've been having some big issues with my memory around 3 years ago. I went to see a psychiatrist 5 months ago and told him about my memory concern, my tendency to stay alone, never really have close friends, don't socialize much and my spending issues, focusing problems since I was a child. He told me that I was a little adhd and a little bipolar. Since 5 months, I've been trying all the adhd pills, I can't deal with them, make my problem worst, I stopped elavil and took some trazodone just for short time, very bad. I tried seroquel, lamictal and the last one is ability and modafinil. I tried all of them for one week, 2 weeks or 1 month. Now it seems I lost all my short term memory. I can't describe my problem, it is horrible, scary. I stopped elavil and I keep Effexor only at 75 mg because Effexor is a killer, impossible to stop that one. My brain is ready to shut down, I can't even remember for example if I copy something on internet, I don't even remember what to do next, I have to think and think to paste it on Word sheet. I close the door of my car while the car is still running, I do things without thinking cause I can't think. Very strange but I could still writing and talking as before but my vocabulary in my both languages are getting less. But I still can speak fast but if I stopped for one second I forget what I was saying. I can't remember any names, so embarrassing to ask over and over. I can't focus on anything. Please help me, tell me anything, what should I do? I've been going to the doctor for 5 months every 2 weeks to change medication, last week I got lost for a good 20 minutes, I was keeping driving up and down the street don't even realize it was the street cause this time my gps was not working. What a mess I became. I look young, I am young in my thinking probably because I am into arts. No illegal drugs or alcohol. Please could someone help me, I am in deep despair of losing everything I've got which is my brain. Nothing else matter only my brain. By the way, I am slim and I eat well. Fruits every day, vegetables. Now I am taking ginseng belova, omega3, b2, 12 etc. I go to gym once in a while, not too often. HELP!!!! Thank you.
