I recently received a double paycheck for going to professional development. I have plans of putting a down payment on a house within the next 6 months.

I blew through $2,000 in 3 days on online shopping.

I was always in denial about being diagnosed with Bipolar II, now I'm not.
I started on 25 mg of Lamictal almost 2 weeks ago. However, my impulsiveness is still there. I'm not manic, as I haven't been overly happy. If anything, I experience lows still. Not deep lows like before though.

How do I break this habit? It's making me feel tidbits of shamefulness and guilt
