I've been through a really bad patch lately, and have just cut the deepest I have ever gone. I can see a lot of fat tissue and it's slowed down in bleeding, but after about 30mins it's still bleeding a bit...My question is, when should cuts get stitches? I've googled it and I still have no idea if it needs them... I'm too scared to go to the hospital as I live with my aunt and she'd freak out if she heard me leave or whatever and I hate needles... I'm just so overwhelmed and scared and I don't know what to do

Does anyone have any tips to stop? Anything to do instead? I'm so sick of this horrible habit, especially after almost 8 years...:'(
