Lacking Self-Care

For some reason, I haven’t been taking care of myself like I should. I have trouble brushing my teeth because I feel like I don’t have time for it and I always say “I’ll do it tomorrow” and never do. Now I’m developing really bad cavities. Showering is also something I haven’t done because I feel like I’m so busy at night because I work late and when I get home I usually do homework and stuff and I’m usually to tired to do anything after I’m finished. Again, I say I’ll shower in the morning, but I sleep in so late that I have to get ready for work as soon as I wake up. I’m concerned that it could be lingering depression, which I’m worried about. I’ve been having it pretty rough lately and haven’t really let myself deal with it and I don’t want it to manifest itself as depression.
