I think it is important to slow your activities as an ms before just quitting. Same for meeting pets. Miss one or two or get someone to fill in a few times at the last minute so they get the idea that you are struggling. Then after awhile you can tell them you would like to reduce your duties to deal with your personal issues.
The deal with fading is that it takes time. Its not for everybody because to truly try to keep the relationships you have made you need to go slow.
