Sit yourself down, talk to yourself. Is there anything immediate and effectively guaranteed that you can do about it? I believe no one man can without sacrificing their life of potential, so that would be a bad gamble. You are a human, you can choose. You can choose what to care about, what not to. That sounds easy. It's not. The nature of the brain is to go with simple thoughts, think about things that are easy. And to fight the nature of your being is very hard. Every moment you need to make a choice. A choice to stay on your path. Know your goal in life. And work towards it. There will be countless tragedies and blessings along the way, but if you stop to care about everything in this world, you will never get anywhere, because there just is so much. A concious being of today has too much information. They do not know what to do with it and how to organize it. Every sensory input you take, think about it before worrying, will this help me in my goal? No? Then discard it. Chess has a principle, you assign values to the pieces, A queen is a ten i think, a knight maybe 8, and that way you can choose which one to loose when you are in a dilemma, assign values to things in life too. And finally, stop looking for reasons. There will never be a reason good enough to do things. Dont addict yourself to the end of the journey. Think, can you live your life happily without studying? Here you have to be atleast 22+ to reasonably know the answer. if you can, then just give up, otherwise, you have mo choice. And what good does it do to cry over spilled milk. That only wastes time. Get it done. Tomorrow you'll want more motivation and support if you keep depending on it.. and it will never be enough. Everything dulls over time. So stop looking for reasons, and do what you must know that you have to do. I hope you be alright.
