(((Ryask))) Obviously he cares for you deeply otherwise he wouldn't still be around. Maybe he doesn't completely understand or maybe he's just overloaded too. I often use the term "mentally exhausted" or "emotionally drained" to explain that "I just can't do it" feeling. It seems to help the people around me understand more how I'm feeling and how to help (or not help...just leave me be).

I understand your frustration. I used to be a complete extrovert, always going and around people before the bipolar disorder got bad. Now I need time alone to recharge and I've had a lot of trouble understanding that. Good luck with your situation. I hope you feel better soon!
