Hi IM,
I just wanted to say welcome to the forums and that I hope you can find the understanding and support you're looking for here. And I am so sorry about your friend who died. It's incredibly painful to lose a friend, and the circumstances have to make it even more painful. I commend your courage in defending her. I have struggled with suicidal thoughts on and off through my life and I agree with you that sometimes it can just be so dark and painful, that dying can feel like the only way to escape the unbearable pain.
I don't think you'll end up like your friend because you've already done the most important thing and talked about your feelings.
I volunteer for the Contact crisis line in Syracuse NY, which is confidential hotline that you can call and talk about anything that is bothering you. All of the volunteers are trained in discussing suicide and how to help someone (one of the first things they teach you is being able to talk about it is so important to NOT doing it). Although I do want to make it clear that suicide isn't the only reason to call, actually its a very small percentage of the calls. You don't have a location so I'm not sure if your in the US but if you are and need someone to talk to the number is 315-251-0600. The line is manned 24 hours a day, 365 days a year, there is always someone available to talk to. The volunteers are wonderful people and if you need some immediate support, this can be a really good resource.
I'm including a link to the website below in case you want to learn more about it. I'm looking forward to getting to know you.
