HELP!! A little TMI

Okay so for a couple weeks I’ve been bleeding every time I poop and I’ve googled many reasons as to why I do this but it said it’s caused by a anal fissure (basically a small cut that’s located on the outer edge of your anus that opens every time you poop) and I’ve asked my mother if she could take me to the doctor just to check it out (btw I’m 15) but she said no because it isn’t that serious, but lately I’ve pooped and it feels like nothing was there in the first place! I don’t bleed or it doesn’t sting at all! So should I be worried about it or am I overthinking it and if I should be worried about it can someone give me some tips on how to get rid of it!!!
