shewolf is right, being sensitive isn't a bad thing per se, but it seems clear that you feel you are indeed 'over-sensitive'. Well, good on ya, hon, recognizing this is half the battle. If you feel it coming on, take a mental break, breathe deeply, and move on. The feeling will pass. If it doesn't, don't take it out later on hubby.
It's probably stress-related, so just do what you would normally do to relieve stress, and sex ain't too bad
Another suggestion for the homefront: Make a list of the reasons you feel so down. Just spill onto the page, and look at it later. You may end up with a huge list. When you are calm, go through the list and ask yourself which things are worth getting so upset about? If they are unworthy of upsetness, cross them off, one by one. See how short the list gets, and be honest with yourself. If you come down to a couple of real issues, discuss them with your hubby.
I'm no expert, I just know that at one point, this worked for me. :wink:
