You coulld say i am unstable since my divorce 08/03, battaling depression, alcoholism, low self esteem, self loathing, and occasional suicide. So of course, going back seems like a quick fix.
This statement convinces me all the more that you should seek counseling. The things that make you so unhappy originate from within. They can be repaired, and you can be happy - but you have to take the necessary steps in that direction. There is no "quick fix".
