a suicide might be the exit just for you,
but think about the people who will be dead from inside when they hear the news. They will be dead for rest of their lives.
the best way out it to share your feelings with a person you can trust, talk. And you will feel lighter.
and when you look back to this day after years you will see how wrong this decision would have been.
take a longggg break, go for a hike, and come back reenergized. My thoughts and prayers with you.
