life is pointless, everything is pointless, we are merely the product of a natural process with the binding of certain elements to create complex organisms. you are as biologically valid as anyone else. There is nothing to do, there's no reason, in reality, to do anything. Now i know this can seem morbid, but you need to drop the constructs of your perception of your universe. Trying to ope with this in my younger years got me very much near the description you have depicted. but ultimately i found strength in it. There is no reason to do anything, so you are completely as liberty to make your reasons for anything in this world. there is not good or bad, evil and holy. there simply is, if you want to do drugs, do drugs, you will move on and time will pass, opportunities will arise and the world will be a completely different place relative to where you are now, time has a way of helping all perspective issues. Nothing is sacred, anything that can physically be done, can be done. we are all able to do anything if its in this objective reality. finding reason and purpose is fleeting and will usually just make you listen to lies.
