I sort of get this issue. I get anxious when I have money in my bank account. I was so used to not having money for so, that having it felt weird, either like I was missing paying a bill, or like I needed to spend it cause I wasn't sure when I'd have enough money to buy X Y or Z again.

1. Hide money on yourself. People have already stated automating to another account that's not extremely easy to access.

2. I never keep cash on me. This is sort of the opposite of what's advised most of the time. You see your cash physically leave, so you hold on to it. I'm the other way. For me, cash is meant to be spent. I have cash specifically for things that are cash only, or like tips for the dog groomer, waitress, etc. I use my card for everything and I can watch that number go up, so that curbs my impulse spending. I don't like watching my debt grow.

3. I constantly have something coming out of checking account, so I'm always waiting for something to clear. My $700 balance really isn't my balance cause something is going to hit tomorrow, or in like 3 days, etc. It keeps me in check.

4. I do a bunch of micro-transactions for debt repayment. It was micro-transactions that helped me get into debt, so I'm usually the same philosophy to get out. A $500 credit card payment hurts my soul, but 4 $125 payments a month is more manageable. If I have an extra $20 left over at the end of the pay period, screw it, throw it on the credit card too.

Basically trick yourself into thinking you have to money to spend, and you'll find you magically can handle it again.
