Did some embarrassing stick-and-pokes, but can only cover them up with more stick-and-pokes...

I, like the fool I am, thought that I should start doing stick-and-pokes as an alternative to self harm.

I am broke so I can't go to a pro. I want to cover them up with more stick-and-poke myself but am struggling for ideas with these symbols. Each is about 3/4" big. Everything I come up with is too ambitious for my skills so I'm looking for any ideas or advice. Any feedback is appreciated.
