How do I spend less time in the bathroom?

I always spend at least 5-7 hours when I go to the bathroom due to constantly being distracted and getting lost in my mind, I’ve tried keeping a digital clock on the wall and having constant noise while I’m in there but it just doesn’t work. Eventually I couldn’t take it anymore and started eating only every few days which I’ve been doing for about 3 weeks now, I genuinely have no idea how to fix this since medication and therapy aren’t an option right now for personal reasons, what else can I do?

Sorry for bad grammer.
