Need advice on how to switch domains from full stack dev.

Currently a full stack dev 1yoe , product based MNC. Paid very average less than tcs digital. I'm facing heavy work pressure (12 hours easily everyday) + war rooms in weekends cause it's a super crucial project. I don't like it a bit , and I've started researching on how to switch to cyber security, cloud , Ai , data analysts roles, I'm so clueless and feeling overwhelmed on leaving this job , cause the pressure and no benifits part is not working out. Can any seniors guide me on this , if they had escaped and switched domains. Plus I don't see myself doing fullstack anymore cause they have destroyed my confidence by constant yelling in every standup meeting. Thanks
