This is the problem with the mind, the mind is constantly thinking of many things, thousands of things. This creates stress, worry, fear, anxiety. This stops us from living a life of peace. Therefore, it is very natural. You are not the only one who is thinking thousands of thoughts, most human beings are. Death is not the solution to this. The solution is to silence the mind, the solution is to make the monkey which is jumping from thought to thought into a monk. How do you tame the monkey mind? By cutting its tail the EY that is ever-yelling and ever-yearning. Death is not the end, because death is only of the body. The Mind and the Ego, the ME will not die. It will be reborn in a new body only to continue living like a monkey. Therefore, death is not the end, it is only a bend, but the way to transcend is to control the mind through the intellect, through the realization that you are the Soul.
