When I had a manic episode at 15 I put a deposit down to get a tattoo but my mum found out and told them my age. When I was 18 and manic I got a tattoo across my lower back I absolutely hate it and wish I'd never done it! During my hypomanic episodes I got my lip, nose, tongue and navel pierced but took them out like a year later. Mania and hypomania can make you spontaneous. Glad you don't regret your tats
