I recommend doing part time college and part time Yeshiva. You get to continue learning but are working towards a parnassah opportunity. There are a few reasons I recommend this:
1) Your family may experience economic hardship and have to stop supporting you. If you are trained in a profession, you can go right to work
2) Its a lot easier to finish your schooling pre-marriage/children. It will also make you a better catch (you can learn full time or work to support your family).
3) You seem uncomfortable with the concept of living off of others. Kol hakavod! But remember, if your family wants to support you, and you aren’t taking advantage of them, then its ok to be supported.
Good luck with your decision.
