So sorry to hear of your story. Many of us have suffered these feelings, I was on medication for years suffering from depression brought on by the guilt I was made to feel. I know no-one is perfect, but I was constantly striving for some perfection in everything that I did. People took advantage of me alot with this. When I to look back I see how I was drawn in to all of this, and it still hurts to see how used I was.
Now years later down the line, sack the medication, sought help, was on ward after ward. Finaly my thoughts are in order, alot stronger, take no nonsense from no-one, and most of all my personality is on track. My best quaility, my humour was stifeled in case I said a word wrong, or something that someone may take as an offence. I am happy now. I hope and I am sure that you to will regain this happinessCherish what you have now, try and forget what you may have had in the past. If you do not, it will screw you up more, and they are still wining. In time people will take you once again as they see you, and you will get back more than you lost. Take care of yourself. You are not on your own. Lisa
