I understand your concern.
It sounds alot like my sister. She always blames herself for all of her boyfriends leaving her but in the sence of reality.. it was THEM!
The one thing you cannot do is make yourself sick thinking you are the bad person.
There is a special guy out there for everyone (i seriouslly believe that) and once you find him.. you will know!
The key is to STOP looking so hard! Let him come to you.
He will find you when you least expect it!
I was on 3 different medications at one time for my anxiety, depression and irratability and I found a guy and I thought he was the center of my life.
Its not always so.. especially when your on meds. The meds in my case shadowed how wrong he was for me.
Coming off your medication is something that should be done under a doctors' care just in case you are doing it too fast! You dont need to go into a relapse and have to restart it all over again. Take it slow.. it will happen!
