I also suffer from OCD, now Zoloft does cause memoroy loss I do not know if it is permanent, with regrds to amphetamines, I have never read anything about memory loss.
Stop for one minute and think how many children worldwide suffer from what you did and grow up to be regular or "normal" persons.
Know you being hypochondriac and also suffering from OCD let us say it is more than just a ·dramatic" state of mind to be on, to tone it down a bit .
It is all in our minds... and you are educated and you know that are our minds are very, very strong and can deceipt us anytime they want..and also as I am sure you are aware we are our own worse enemies... with all these mental conditions it makes even worst. For regular perons it is hard for it is tremendously difficult to deal with... we must be always prepared also awared of who and what we are and accept it..do not fear it, it is in us... part of our very essence.
I am 41 years old manic depressive, paranoid, anxiety, OCD, insomnia, etc..that is enough for know,regarding myself.
This is what you should do ... from my experiences in this so called world
Learn to control your mind, your emotions, your feelings , your fears..do not let them control you... for if they do you are ... I will not say... because I am here to help you within my means. It is very hard to achieve the only way to learn is to fall and get up again and again and never ever give up and every time you get up you gain knowledge, experience ,courage and strength no matter if it is good or bad as Enistein said "there are no good or bad experiences for they are only experiences", this means always rescue the positive things in life.
Never struggle through life´s path always walk with your head held up high..you are in control and so am I... not our conditions which if we fear and do not accept make us weak. That is all for now. from a caring individual
