the mania-it's got a mind of it's own. it's not your fault. sadly i've made some serious mistakes while manic regarding investments in the past and lost a lot of money that didn't need to be lost. when i'm manic i sometimes don't know it and have misguided judgement. it sounds like that's what happened to you. try not to beat yourself up about it. be kind to yourself. know you are a good person with a challenge of mania sometimes. the bathroom still stands. there are solutions once you feel better. hugs.. you can paint over the drywall, wall paper and all. you can recaulk those areas.
oh forgot, run all this by your T...if you are bipolar meds can get this mania in check.
