All of you have written a nice posts for you to spring out of this state and do something about it.
GOD neither punishes nor tests. He/she also cares. We are the ones who do not care about ourselves, thus get to this stage in our lives. Don't blame anyone. Take the responsibilty for your own actions.
Dave has written a very nice post. I am giving you some other ways to help yourself, but you have to take steps by yourself and one at a time.
1. Do a colon clease
2. Do a Liver Flush
3. Eat raw plant based foods for a month
4. Apply castor oil or sesame seed oil on your entire body twice a day.
5. Walk 20 minutes everyday (fast brisk walk)
Eat no junk foods, meats, fish, chicken, fried foods, etc.
Forgive those who bully you or are nasty to you. Ignore them because they are ignorant.
Keep posting here to get help and inspiration.
Sorry to be blunt, but I do not bit around the bush.
