Staying home from school

Can anyone relate to this? I’m really struggling and I can’t explain it to my mom so on the odd days I’ll find an excuse to stay home. Like today I don’t feel good. Other days I find any reason to even go home early. But then when I don’t go a part of me feels guilt? Even tho I’m miserable there and it is destroying me. Is anyone in the same situation? And does anyone have advice? I’m struggling so bad
