What ever works and it will be different for everyone. For me, i have just tried to stay outside myself. It has been rather easy as since 2017, when my PC popped up, my wife was suffering from COPD and slowly going down hill. As a result i became caregiver, house and yard husband which will certainly take your mind off of internal concerns other than I've got to survive to tend to her. It's worked so far but I lost her just over 60 days ago. For a very short time, I thought I'm finished now and considered giving up. She would not have wanted that so I'm back. No more depression and will continue to fight it. Oh, forgot to mention, when she died, we only were short 28 days from celibrating our 61st anniversary.
