I don't have a partner, but my parents really want me to tell them when things get bad. Last time it got really bad, I called them from the psych ER to tell them I was being admitted-they had no idea that I was struggling! It scares me more than anything to open up to someone and make myself vulnerable.
MM, it is really sweet that your H holds you while you sleep. Shows that he loves you and cares about you and wants you to stay around.
