always feeling guilty??

i wasn’t sure what group(s) to put this in, but i’m 14 and i’m CONSTANTLY feeling guilty. i rarely do things wrong, but it’s not even that. i’ll feel guilty for making plans with my friends because i’m leaving my mom alone, i feel guilty for telling people things in my life, i feel guilty for leaving friends houses, cousins houses, family basically anyone im with and i feel guilty for leaving my dads house cause i’m leaving him alone. it’s march break and i want to hang out with friends as much as i can but i feel so guilty about it! about not staying home with my mom, she’s not sick, disabled, nothing like that. i don’t know why this is happening, but i feel the need to apologize for everything i do, like even when i’m sick. this is getting on my nerves and affecting my everyday life. i don’t know what to do. i also constantly have a fear something bad is going to happen to my mom, or when i leave her she will be really sad. i hate feeling like this so much but i don’t know what’s wrong.
