At some point most of us experience this emptiness and how it affects our life in general, and like domino effect those daily routines end up being jeopardized by us whether this is conscious or not.
I have just few brief thoughts about suicide and that it can go in different ways. You could make your problem everyone else's problem, you could end up with disabilities for life. Or you could simply go to a worst place. All the options are irreversible so it has come to my attention that this is definitely not the solution.
Despite of risking being cliché I must tell you that you are in control of your life and you choose what's going to be. In a way or another that's what growing mature is all about. Learning how to deal with challenges and suffering experiences and making a way to handle them and still have means to be yourself and do things in your way. Important actions that you could actually come to appreciate.
Money comes and goes and from my experience I can tell that this is something that can be resolved with time and possibly with some guidance. Do you have someone that you could share your problems with? Have you thought of going to a psychologist?
Therapy is a wonderful thing and for me it's like getting mature in a smaller amount of time. You start to see yourself and realize you want to change. How and when depends on you. And as you said yourself, you need to get it out.
Life is tough I think we all can agree with that but maybe we can learn that it does not have to be that tough on us. Not tougher than it is already.
Whatever is your next move, remember that there are people who cares about you. You are still young and have a lot to live for and remember us from Bluelight where I welcome you to start sharing and we'll be glad to join in and help.
Wish you better days. And remember that life is all about phases, this one is just part of the package!

Good luck!
