This is probably something you should discuss with your rosh yeshiva and/or rabeim.
That said, here are a few questions:
-Are you truly learning well?
-Are your parents happy to support your time in yeshiva?
-If you stayed in yeshiva with the goal of eventually going into chinuch as a rebbe, magid shiur, etc. – would you be less uncomfortable about accepting your parents’ financial support?
-If you were independently wealthy – let’s say you won the lottery – would you then be OK with not getting a job in the secular world?
-If a rich philanthropist would support you while you worked full-time for an organization that did chessed – let’s say Tomchei Shabbos, Camp Simcha or the like – would you be comfortable with such an arrangement?
-If the answer to the previous question is “yes”, isn’t getting supported while learning similar, especially if the objective is to eventually teach and help others?
In both cases the financial help of others would be allowing you to spend your time performing mitzvos.
As someone who’s been working in the secular world for a while, I urge you to recognize your unique opportunity.
(I didn’t go to kolel mainly because I felt that my learning wasn’t serious enough that it would be fair to ask someone else to support me.
Even nowadays, if I was to win the lottery I’d probably spend a couple of hours a day learning and the rest volunteering in a chessed organization – I’m just not that good or that serious a learner.)
