First off I’m eternally grateful for my friends. However lately I just feel like I’d be better without them. I work around 53-54 hours a week and also go to the gym 5-6 days a week. I’m so tired from working and working out that I just want to do nothing but be by myself at times. However my friends constantly want to hang out and when I say no they guilt trip me and I end up going. This has been going on for a little over a year and frankly I’m tired of it. I feel like they do nothing but waste the little time I have to myself nowadays.
So should I just cut my friends or just suck it up and keep hanging out with them?

Meh friends are both imo. They either help you or, like you said, waste your time doing nothing. Pick your friends wisely.
