Do first Identify what your problem is. That would be your stepping stone, knowing the problem is also making a solution into it. Everyone is suffering from their own problems, it could be with regards to their academic grades,family issues, relationship conflicts and even personals. There's no way to instantly quit a problem and surely, it won't be a solution. It would be much better to find a solution than to just give up and quit. Whatever your problem is, there would always be a solution for it. I have before encountered huge problems and although it seemed hopeless before, I have somewhat managed to get over it and be a better person at this moment.
Achieving peace would be difficult at this point. The world we are living in is surely something to consider as toxic. Everyone is arguing, war in some countries and lots of deprivation. It does ring a bell for me. You have mentioned quitting your problem, and having a peaceful life. If you are referring on finishing your own life, brother, don't be foolish. It will never be the solution and rather make the situation even worse. No problem is bigger than you yourself. It is you who would be able to help yourself. Quitting means you are weak. Peace from quitting? that will just yield to burden. Do think twice buddy!
