Choosing between open practice of islam now or delaying It for education

Assalamu Alaikum wa Rahmatullahi wa Barakatuhu, I am a young man in Ontario, Canada who reverted to Islam in December 2024. My father is a Hindu who is extremely hostile toward Islam and has a well-established pattern of financial control and psychological abuse. During my undergrad he disowned me over a minor argument and withdrew all tuition money from my bank account, forcing me to complete my degree on government student loans. Shortly after my conversion I experienced a severe psychotic episode and was hospitalized for one month, during which my father confiscated my phone and laptop, forced me to work unpaid in his pharmacy for all of 2025, and assigned me a psychiatrist who mocked Islam and reported everything back to him. Alhamdulillah I have been stable on medication with no symptoms for over six months. I have already received fatwas from two separate scholars confirming that concealing my Islam from my father in this situation is permissible under ikrah and that accepting his financial support is halal. My iman remained strong throughout everything alhamdulillah. I am currently enrolled in a dental hygiene program in Ontario. My father is paying part of the tuition. Upon graduating as a dental hygienist I will earn a sufficient income to live independently and practice Islam fully and openly. My long-term goal is to apply to dental school after completing hygiene school. My father has expressed willingness to fund this, and the tuition would be approximately $500,000. There is no realistic path to dental school without either my father's money or riba-based loans. However, if my father were to withdraw his support midway through dental school I would still graduate as a dental hygienist with a protected income floor. Crucially, dental school would be abroad, meaning I would be physically separated from my father and able to practice Islam fully and openly during those years — the concealment would be limited to phone calls and visits rather than daily lived reality. My question is this: I am torn between two paths. The first path is to graduate dental hygiene, move out immediately, and begin living openly as a Muslim with a sufficient independent income, leaving dental school behind entirely. The second path is to continue concealing my Islam from my father only during calls and visits, accept his funding for dental school abroad, live openly as a Muslim during my years of study, graduate as a dentist, and return to Canada as a fully independent professional with a much higher income. Both paths lead to me eventually living as a free and open Muslim. Which path is wiser for my deen and my dunya, and is there any Islamic reason I should prefer one over the other? I suffer from severe waswasah and am seeking clarity to settle my heart and move forward with confidence. JazakAllah Khair.
