Hello Tammy,
Remember that this will pass. I know exactlly how you feel, I suffer bouts of some pretty bad depression (bipolar induced) as well with anxiety that doesn't feel like it will pass. You did the right thing by posting about it on here, it is always good to get out what you are feeling insteed of holding it in and making it worse. Try not to isolate too much, if that seems too hard, which I know it does, then just keep posting on here...let it out. Check out some meetings and talk how you are feeling. There also are DA (depression anonymous) meetings around as well as NA and AA. Perhaps you should focus on yourself for right now and less on helping others. Addicts tend to try and help others in order not to have to focus on their own problems. It could be a trigger. But you deffinitley have been a great accet to this site and have been SO helpful to many. Keep posting, you are doing wonderful. Remember that this feeling will pass!
