ineedhelp02, Hello and welcome to PC.
You are experiencing some very difficult things and at your age it is very hard to figure things out. I really want you to know that you matter in this world and you are not invisible. You have much worth but you just can't see it right now. You might be feeling the effects of depression. Is there anyone who could get you to a doctor? Is there a trusted adult who could arrange this for you? I really hope that you feel better and know that there are people here who you could talk with and get some great advice.
