Its good to think positive, try not to give up. Its really difficult when you want to get better and if environment is a stressor then its not easy. You know what is good for you and what isnt and yet finding a good environment to heal isnt always easy. It doesnt have to be a rehab centre, it could be a hut in the himalayas, a room in the house of a good caring friend - its different for everyone. So take care
