Zelleta pill and periods to stop

Started this purely to help my skin after experiencing constant hormonal breakouts, which it did clear up and meant I could eat however I wanted basically with no consequences on my skin (sugar and fatty foods). However I feel as thought the pill has really dampened my mood making me low level depressed all the time. Also experienced a decreased sex drive and lots of hair loss - but still unsure whether these are directly related.

Since taking the zelleta pull my mood has gotten a lot worse. I catch myself crying over little things I would have never cried about before. I used to take the cerelle pill which worked well for me but now I get irritated easily and lasch out at my boyfriend a lot.

Switched to Zelleta (Desogestrel) from the combined pill because of side effects. Had one unusually long period (9 days) one month after starting Zelleta, after that my periods stopped completely and I only had minor spotting every now and then which almost completely disappeared over time. I gradually noticed a complete loss of sex drive which bothered me a lot and I ended up switching to non-hormonal contraception instead because of this.
