I, too, am going through depression. My husband and I are separated but still living in the same house. We are getting a divorce after 14 years of marriage. I am angry and sad. He cheated on me and it turns out he is gay. This has been one of the hardest things I have ever had to deal with. I've even thought of suicide. I'm in therapy but one hour a week just isn't enough to get through my feelings. But it helps. There are support groups around but they are all church affiliated and I'm just not really religious. I don't have any family or friends to help me through this.
If you can find ANY support group...go!! Also, just because a support group is in a church does not mean it will try to get you to join,etc. Many times, they are held at churches simply because they have the space. Just try it once, and maybe you will connect with one or two of the people! You don't have to go back if you don't want to, and it will, at least, get you out of the house one night!
