My moods are very up and down at the moment. I can be really cheerful but then something happens (like the baby thing) that makes me down in the dumps for a day or two. I try to think of it as 'just another Crohn's symptom', it's not really me, and just like my other symptoms are worse on some days than others, so are my moods.
I also enjoy a good self pitying cry now and again, then when I've finished I'll do something positive to put a 'full stop' to it. Like I might walk the dog, or have a shower.
