I sometimes feel like death would be a restart button
What makes you feel like death is a restart?
Death wouldn't be an ultimate game over.
You should get help if you feel suicidal. Death isn't a game and has permanent consequences, you can't undo killing yourself.
I'm not suicidal, things have just been rough recently so I am thinking about it.
I am sorry that you are having a hard time but you should see therapist so that you can feel better. They might be able to help you take steps to deal with your problems.
