Unless you got sickness which is 100% no cure and even pain killer also useless anymore then you can consider do that.
I believe there's many people have had that thought before whenever they were having breakdown.
But what for?
Because you lose someone who don't love you anymore? You should Thank God.
You got a huge debt unable to pay? Get a job to pay.
You lose hundred thousands (or maybe millions) within seconds? That's the consequence for taking a high risk and being too high profile.
You lose friends and families understandings? Figure out what's the problem then improve yourself.
You can't be together with your love one anymore? If that's the fact, accept and move on. Love is not the whole part in our life.
You lose your spouse or loves one? Pray that he or she can reach to heaven while you should stay stronger for not letting the person loves you worried about you anymore.
If it's just because of other matters you are doing this, I'm speechless my dear. You are tough and smart, with a pretty face as God's gift to you. I believe you know what you should do to really solve the matters, and doing this just can help nothing or make it even worst.
God closed you a door, he'll open a window for you.
Take care.
May you be well and happy always.
