resignation dilemma :(

Hello! I just need some of your thoughts about my dilemma.

I'm planning to resign here at my job. I've been here for almost four months but I cannot stand to work with my boss anymore. Professor siya dito and most of the time sa akin niya pinapasa ang trabaho niya mostly school stuff na wala naman akong alam dahil hindi ako professor and I don't know how that process works. Of course, nagtatanong naman ako sa kanya but there are times when I ask, naiirita siya. To add to that, simple mistakes make him so angry. Sobrang toxic din ng environment ko up to the point na sobra na ang stressed ko which makes me so irritable and sometimes sick.

Now, ang idadahilan ko kung bakit ako magreresign is babalik ako sa former school ko for my master's degree kahit hindi pa naman. I just really need to get out. Im not really sure on the resignation process kung magrerender pa ako ng two weeks notice since wala naman nakalagay sa contract ko.
