what i gather from what we've all posted here is that you're encouraged to post whenever you need to - up or down, good or bad - as long as you're not attacking others in your posts...
if it's 2 a.m. and you're looking back on a day that went horribly awry because of volatile mood swings, come here and talk to us... it might not "fix" things, but talking through it will help... and with the large community that gathers here, you may find many others who have had (or are currently going through) similar experiences... because you're talking to and venting with people who've been there, done that, you'll also get real advice that's been tried and tested by the rest of us on how to best manage your illness along with approaches for attempting to repair damage done to relationships & overall generally helpful suggestions for having a better and hopefully more balanced life...
don't give up & don't be afraid to share what you're dealing with... we're all here for you

we might not respond immediately... but most everyone here just wants to be able to lean on each other & have other people who "get it"... because sometimes that makes all the difference in the world
@Chihuahua: as far as your daughter's nail biting... that's how a lot of the world deals with stress.. keep an eye on her & try to be as supportive as you can ... and if she starts to exhibit other signs of stress, don't be afraid to seek out professional help... family therapy isn't the worst thing in the world & sometimes trained pros can get through to little kids & help them express themselves better than the rest of us... just let her know that it's ok to share how she's feeling & that when she's not ok, for whatever reason, you're there ... there's only so much you can say to a 4 yr. old because their mental capacity is limited still... best advice... lots of hugs & smiles whenever you can
