I agree with Suzy, My daughter who is Bipolar1 ultra rapid cycler, can spend thousands in two days at least she did before she was medicated properly. I still always get paranoid when she goes shopping..LOL. Maybe your just OCD ing about the tank more than mania setting in. Just be careful.. maybe you could find someone else to partner up with that has to agree with your purchases for a while... Maybe that will keep a lid on overspending.. I hope your taking your meds.... that is usually where this starts.... good luck to you.
