Spiritualy rooted diseases

Hi,
This may not be the correct place for this question, but I'm going to try it anyway.

According to many/most articles I've read FEAR is the root cause of most all diseases. From anxiety to something that begins with a z... Which I personally believe.

So, my question is how does one get rid of the fear??????? At the rate I'm going I should have died years ago from almost any known disease. I know forgiveness, self love all the reasons, but I suffer from severe anxiety, panic attacks, Depression (comes and goes these days), OCD, I have chest pain daily, (I'm 35) ect..... I can't just stop the fear. It took me 35 years to get to the point I'm at beginning in early childhood. I could spend the rest of my life forgiving myself and others who I feel have "wronged" me. I have a very difficult time "letting things go" I do try. Just looking for some spirtual advice and please don't tell me to hand it all over to God because I have and for some reason I keep taking it all back! LOL

Thanks for any and all replys.
Love,
Libra
