I would suggest therapy. I went one earlier this year and "graduated" last month. They may suggest doing meditation which I always thought it was dumb but once I did it every day after work and it has been a game changer.

You may always want to do a trick I still do which is at the end of the day before heading home is to writing down what I couldn't today and will need to follow-up tomorrow. Helps keep you organized and makes you less worried that you will forget tomorrow.

Everyone is replaceable at their jobs even presidents and CEOs. Put in your time at work and be selfish at home to enjoy your friends, families and hobbies. You are your highest priority, not your job.
