Hello,
Yes, MickeyCheeky is right Chocopiano27, he doesn't sound supportive at all. You have trusted him with your deepest inner thoughts and feelings, your past, you open up, and he gets annoyed with you. He doesn't embrace you until you cry. No, I don't like the sound of that because at the very moment you need him, he does a 360 on you!
Nevertheless I think you've fallen in love with him and that, combined with this rollercoaster ride of highs and lows, can drain you of energy, Chocopiano27. Don't let the thoughts of dying linger in your mind please and cling very much to your life instead. I'm sorry to tell you but you'd be better off without this guy in your life. You need supportive people instead.
If you still feel awful, struggling, keep reaching out here at PC if you like. There are many forums that may be able to help also.
Stay strong Chocopiano27, you can get through this.
