How to Deal with Toxic Manager

I went through the same and went overboard to please such a person affected my mental health and had to take a break. Please focus on your health. Block time for yourself outside of work. eat healthy, workout and meet people (have fun). Working with such people will always be draining, so get in and out of conversation with them quickly, be to the point, clear. Reduce exposure and heat as much as possible.
Keep things on written comms as much as possible MOMS, journaling (helps your cognition and tracking) etc. Remember it is ok to take help or do what is best for you.

Unfortunately you will need to bear him till the time you desire to stay in the firm and quit once you feel the moment has arrived. Corporate frustration is very normal and is difficult to bear as well. But there's no choice until the moment to switch has arrived.

This is 90% of the workforce. Job change can't be the solution. You may witness his big brother in a new job. Look for IJP, learn how to manage upwards, be visible to your skip level bosses, pick high dependency projects, focus on things which you love outside work like yoga, gym, kids etc.

Unfortunately, nothing can be done to deal with such managers. May be you could try moving to other project/team?

Let me know if any solution worked for you. I am facing the same any disagreement shifts to major arguments.
