Thanks for the reply on my thread. I thought I would add to yours now. My heart goes out to you and your son.
It is hard to put yourself first when you have been caring and trying to help a CG. I hit my rock bottom last month and told myself no more. I had to change my life because my husband was not going to and I can not live like that anymore. I have started to work out again. The cardio is really good for anxiety and depression. I meditate and do yoga and write in a journal. I can see a difference in myself and notice that making decisions and saying no becomes easier and there is no second guessing my decision. It is hard to let someone you love make these poor choices and then beat themselves up over them but we have no control over that.
Focus on yourself and do what you can to relax and bring you some balance to your life. Have you tried talking to a counsellor who specializes in gambling addictions or going to Gam-Anon?
