Where can I put my money that won't make me angry?

Nat, if your overdraft is costing you anything in fees/interest then your money would work harder in your current account trying to get you in the black. Savings accounts are paying such low interest right now.

With interest rates as they are, if you are a net debtor, then any extra cash should go towards reducing your debts, not into a savings account. If your savings account pays 1%, but your debts charge you 5%, then you are losing £4 a year, for every £100 you have in savings rather than paying down debt.

I seem to recall you're studying at the moment; if you're struggling financially, look into the college's hardship fund.
