“I feel guilty spending anything on myself”

What could be going on

Money vigilance: Fits if spending feels risky even when you can afford it, and saving feels like the only safe move.

Self-sacrifice schema: Could be a habit of putting others first. Check whether you'd spend the same sum on someone else.

Guilt: Check whether spending has wronged anyone. If not, the guilt may come from an old rule.

Money avoidance: Fits if having or using money feels wrong in itself, as if it belonged to other kinds of people.

Conditions of worth (Rogers): Could be a sense that you have to earn the right to want things. Check when you last felt you had.

Scarcity and the bandwidth tax: Fits if the habit dates from a time when every pound mattered and hasn't caught up with now.
