My psychiatrist said I'm to old to struggle with hygiene

I saw a new psychiatrist last week because my previous one I was having issues with getting medication and was feeling our appointments were very rushed. So I saw a new one and mentioned my struggles with hygiene mainly showering, brushing my teeth, hair, etc. How ive been like this since elementary my parents would have to force me to brush my teeth and shower. She stated she would understand if im depressed but I'm too old to be having those kind of issues. And I realized after scrolling through a recent post about someone struggling with showers that I wish that was the case. But it's just sometimes I can't be bothered to do it, I forget, or just lack the motivation. At first I felt she was right but now that I think about I feel like she shouldn't have said that. But I don't know maybe she's right.

Edit: thanks for the replys it really helped im definitely gonna look into finding a new psychiatrist since my next appointment isn't until a month so wish me luck....hopefully 3rd times the charm
