Oh my gosh, you are having such a hard time! I am so very sorry for what you're going through. I know it seems like this will never end, but I can tell you it's not rare to have recurrences and multiple treatments over the time frame that you've been dealing with this. That doesn't make it any better, I know, but I only say that to point out there is a light at the end of this and, from what I can tell, you're not some odd, hard to explain case.
What treatment are you having (forgive me if you've mentioned this before and I simply don't recall)?
You poor dear, I wish I could do something to help. The fact this is bothering your relationship makes it even harder.
Is there anything you can do to relax, to take your mind off things while you heal and your body is coping with this? Movies, books, or the like? If you'd like to join us in the Chill Out lounge(http://www.ashastd.org/phpbb/viewforum.php?f=13
) to hang out and chat off topic, please feel free.
Hang in there, and post as often as you like!
