Communicate
1. Tell them you are there to help them with all of it and they are not alone. They can over come this!
2. Let them know things will get better. Suicide is a permanent fix to a temporary problem.
Offer Help
1. Check up on them to see how they are feeling
2. Listen to their problems and help them out with what may be troubling them
Follow through
1. Check on them randomly just to let them know you care about them
2. Continue to help them and talk to them even when things get better
