Need advice I am so lost !!

to keep it short, I am a F (30) my life right now is a whole chaos. I have to restart everything so I chose to stay in a foreign country (for multiple reasons). First thing I need to do is to restart university, I realised that I don't want to be an engineer anymore so I want to do accountant major. However, the costs of studies here are so high (one session costs at minimum 7000 $), so I have to wait until I get my residency in this country and that will take around 2 years. I feel so frustrated because I don't know what I have to do in these 2 years and I will just waste so much time (I've already wasted a lot). If you were at my place what would you do? are there any stuff I can at least learn in the meaning time?

Ps : sorry if I made any mistakes in my writing, english is my third language
