I've attached my first post. I'll post the previous updates in this thread. This will be my final post. TL;DR I (20F) been in love with my sister (28F) for as long as I can remember, we're extremely close, she's moving far away, and when she told me I freaked out and eventually told her the truth, that I am in love with her and have had romantic and sexual desires for her for many years. She was shocked and disgusted. She reached out the day after and we talked thru things and it seemed like there might be some way to save our relationship, but not now. I have ruined my life.
My mom called me today. I was too scared to answer. She left a message saying that my sister talked to her about "what I said to her." She said that the four of us (my mom, dad, sister and I) need to talk about getting me help. I absolutely cannot do this. I will not come home for Thanksgiving. I am going to kill myself. I'm just trying to think of what final message I can send my sister so that she doesn't feel responsible for my death.
