WHAT DO I DO?!!😓 (HELP ASAP!)

So I was currently doing part time work and full time study (was suppose to finish this university course in 2 years). But now I have changed to working full time and I have to study part time, which means it’ll take me 4 years to complete.

I wasn’t planning for any of this to happen. I’m 20 right now but I was hoping to complete the course when I turned 22 but now that’ll mean I’ll finish when I’m 24. I feel like that’s too old. Most people have careers by then and I’d just be studying.

I’m stressing too much and I just need realistic advice on this....like that it’s ok to study for that long or until I reach my mid 20’s.

HELP ME PLEASE!!
