My husband and I have been together for 22 years. He has been diagnosed with post traumatic stress disorder, chronic anxiety and chronic depression. He was doing alright until he ran into an old friend that convinced him he doesn't need his medication and now he is drinking every day and he has not been on his meds for 3 months. He is beyond difficult to deal with, but I feel horrible at the thought of leaving him, because he literally has no one else in his life to help him.
