I know you said you won't come here again, but just in case... and I don't even care if he sees this because you said you thought he found it, someone needs to tell him. He sounds like a piece of crap who only wants you for sex and nothing more. Sure, you've got problems as you've admitted, but 4 times a week is his minimum expectation? Seriously? If he really cared about you he'd be trying to help you get better, not making you worse by demanding sex and being an immature child when he doesn't get it.

If the meds are affecting you this way and you want it to change talk to your doc about switching to something else or what you could do to increase your drive. If it's not that important to you to increase it, which it sounds like it isn't, then find someone who can appreciate you regardless. Either way this guy sounds very toxic and I'm confident in saying you should get rid of him. He doesn't deserve you.
