Thanks for the introduction, Ra.

It is nice to meet you. I am sorry to hear about your boyfriend - that's pretty traumatic. And if your grief has not been recognized and accepted (which seems to happen sometimes, especially when you are a teenager), then maybe that is part of where your lonliness now comes from.
Talking about it is likely to help you feel better. You are welcome to talk to us here, but please also talk to someone in real life (parents, a school counselor, or go to the ER) about how you are feeling. They can help.
