Is this considered "Suicidal"?

It is not suicidal... It just means that you are strong in your faith and belief of an afterlife. This, generally, isn't a problem, just be wary of others and how they might respond of your acceptance of this. You said you have a lot of friends, which means that they might seek help for you, so just be cautious of that. Otherwise, live your life as best as you can :)
