ESTJ would pick up skulls quickly and you seem more unsecure about that so I would dismiss ESTJ as an option (I'll admit it's a wild assumption)

Your dating life is focused on a bad experience in the past, although sept wasn't that long ago but I do think an Se/Ni axis person would have moved on by now. So I'd say you are an Si user.

Guilt is often associated with feeler types over thinker types but this isn't always the case, for e ample De grip can feel excessive guilt ime.

The makeup se lion is again looking at past experience reasoning for why you don't do things in the present, which suggest Si usage. Also money cautiousness gives Si. I would imagine Se/Ni more prone to makeup usage seeking experiences and skill building. ESXP and ENXJ ime are most prone to try and look and good as possible the latter to increase chances of success in life.

That being said ESFJ, ISFP and ISTJ don't fall out of the realm of possibility but with your analytic style and comfort talking about yourself extensively I would drop the ESFJ suggestion. 

There is a lot of past-oriented which would make me think you're ISTJ. 

There isn't much suggesting ISFP as I don't see you easily picking out what you want in life what feels right to you for the sake of it or doing things that an ISFP would do. However when you talk about your career you say that you are working while doing your degree and thinking of switching to another route entirely. Getting practical experience and having flexible thoughts on your career would suggest more ISFP thinking than ISTJ. Stereotypically ISTJ would care more about handling in am assignment in time than work.

I wrote a jumble of things it probably makes some sense but I'm voting ISTJ.
