I can't relax at all due to my family and idk what to do.

Hello so me (30M) can't relax at all when my family is awake. Every single night I try to game because that is the only way I can relax but I can't do it during the day because my family keeps interrupting my session every 5 minutes which ruins my flow.

I can hang out with my wife the whole day, do chores, watch some bad movie and when she falls asleep and the kids are asleep I try to game for an hour or two (In my perfect world it would be more but I know its not realistic) but she keeps waking up every hour for whatever reason (nightmare, pain, heard the kid which did not make a sound etc).

I'm going so insane because I can not relax for the life of me during the day because I always have to do something or be a social dad but man I just want to escape it all. Idk what to do or why I get so frustrated at night when my gaming session fails, I even lie and make up work reasons to why I have to stay up. I love being a husband, dad and all that but I really wish I could like once a week or something just disconnect from everything and get like 6 hours to myself. ( I do walks and stuff but that doesn't help).
