Lost her to suicide

So I'm 16 she was 14 (I was 15 when we started dating)

Uuuh wtf now... Maybe can tell yall a bit about that day So i go to school and I see her and she had alcohol with her I decided to drink all the alcohol to act cool. So we skip school Then we get back and I leave her alone, then I get pulled out of class and I hear she stood in front of a train... now it's 1 month later... idk what im trying achieve with this post tbh just felt like I should get it of my chest to a couple stranger on the internet
