Is it ok to stop taking the pill mid-pack?

So I've been on Chateal for about 2 weeks and I HATE it. It's definitely made my depression worse and I'm not sure but I think i may have also gained weight even though that's never happened to me with combo pills that have higher levels of hormones. I want to stop putting these in my body asap but I'm wondering if just stopping in the middle of the pack will make things worse- should I suck it up and finish the pack or is it better to stop right away?

Edit: I'm leaving for a year long study abroad at the end of this month, so while I know I should wait the three months and see if my symptoms improve I don't really have time and I'd rather have my birth control sorted out before I leave
