Its a really long and hard proccess. You just need a friend and keep pushing your way  through it. But its been 3 years for me and it still hurts just to walk by them at school.

No you don't but it is a bad idea to kill yourself. You mom prolly just told you that because she wants you to live so she scares you out of killing yourself. Just don't do it at least tell me what this is all about so I can help you out :)

Its not getting enough blood to circulate so the nerves move around causing a tingly feeling so the you know to lift up your foot and let the blood flow.
