Honestly, before you do anything even related to suicide, you should exhaust all other options. Then, and only then should you even begin to contemplate death...and even then, don't you dare actually do it!
Suicide doesn't fix anything, even for yourself...people of most every religion will tell you that it's not of the good (yes, even atheists). It helps no one. If you think you should come out on facebook, then go ahead. You never know who might be supportive.
And always, always remember: even though we've never met, even though we've never seen each other, face to face, even though we may never play games together, or drink together, or cry, or laugh, or dance together, we love and support you.
And I think it's safe to say that most everyone on Susan's agrees with me.
You might not have your first family supporting you, but you do have this one...and I think there are a lot of us.
A hug from every member here...that's a lot of hugs!
With love,
Alice
