Should i take a break

I have been working in a startup for the past 5 months the Work Culture is getting to me. The lead tells me he wants the deliverables at any cost. I am loosing interest in the job by the day and i feel i need a break to reset myself i have started getting health complications as well. I roughly have 8.5 lakhs in my account and by the time i leave i will have 10 lakh lumpsum in account.

Any advice would be greatly appreciated. I don’t carry the burden of marriage and there is 0 loan on me.
