Wow! That's quite a combination of drugs your doctor prescribed. I take zoloft 100 mg. and in the process of tapering off clonazepam. I'm down to .25 - was taking 1mg to 1.5mg before bed because I have a had time sleeping. I am pretty used to the .25 now, it's been at least 6weeks. I took Lexapro once and could not take it. Was like speed to me, I couldn't relax. My new doctor let me know all the negative things clonazepam does to a person, especially as they get older. I am 67. Aside from the the side effects of tapering I am actually feeling much better.
I know it's difficult to live without the meds but IMO you are overloaded on meds. Please try and see a new doctor and ask to detox from a few. Read about your medications to learn more and be able to help yourself some. The best of luck to you on your journey.
