Welcome to this board, Sorry you are here but you will mmeet some wonderful people here and get some great advice. Have you read the resources? I would start with the detach link. It does sound like you H and you are going through a crisis. We all have been there.
Now you have all the tools to read. Let us know how your doing and if you have any questions.
I suggest that you read the entire thread in the resources. You can also pick out some people and read their whole story.
Remember that in the stages of MLC it does NOT go 1,2,3,4,5,6 but can get all mixed up and repeat itself and have more than one stage at once. Depression is the key to the whole thing and it is always present!
