you may want to consider a tax attorney as well.

However I reallyyyy want to get my hair done!

This is it, OP- this is the reason you have a spending dilemma.

you WANT to get your hair done at the cost of $300.

but do you NEED to get your hair cut this month? or is it just that paycheck burning a hole in your pocket?

You need to find a lower-cost alternative to getting that "spending high" that will "boost your confidence".
