Suicide is a permanent solution to a temporary problem

And your problems ARE temporary. Things are not going to stay this way. It will get better
You'll look back on all this one day and realize its was not as big a deal as it feels like it is now.
You have had this secret all your life, now its not a secret anymore. Thats new for you, and scary.
But you'll get used to it. Really. Have faith.

Keep breathing, relax. Do you pray? Maybe say some prayers. A little meditation? Find some people to talk with. Thats good to have.

Don't overreact.
