Not sure

Sometimss during each month I get really depressed and angry and I dont know if its because of my period of it's because I'm really depressed. Overall I'm just not happy with my life but the fact that I only feel this way certain days of the month makes me think my period is the culprit. Does this happens to anyone else?

I really want to know because this makes me feel really shitty and I push away my partner because I start thinking a lot ot nonsense about him that is not true just because were long distance and then I also think that I hate having to work so much every day even though my jobs are relatively easy. Please dont be rude.
