I haven't brushed my teeth is over 7 days....might go 2 -3 days a week on average without brushing.

bathing is the same, I could shower every day of the week, then one week shower 6 out of 7 days, then 5 out of 7 days, then rarely go a week without showering.

I'm 21 and I realized or I feel it's pointless, it's a waste of time, I don't care, it takes to much effort.

no one ever says I smell, no one else cares.

Just started doing this over the last year, I just don't care anymore.

Also been battling depression.

Is it a mental problem to not care about hygiene?
