Do Good, Avoid Evil, Purify the Mind.
I'am in the same case like you, i feel the same, i'am 22.
I realy dont know why i was born, and what to do in this ocean of suffering. In the past thinking a lot about it, and i took decision to "Do Good, Avoid Evil, Purify the Mind."
As i dont need my own life, i dont need this body, feelings, perceptions, formations, consciosness at all, i have never ask anyone to give it to me, so i concider it like not me, like not myself like not i am, and concidering thus i direct it to Doing Good, Avoid Evil, Purify the Mind for the wellfare of these wich it belongs to.
I try to help others how i can, and dont loose any moment to do it the best way. Actualy suffeing of others is the only thing that my life guided by and supported by. If there is some one who want to life, he can take my life - he have a permission.
If beings want - they will feed this body, if they dont want - it will naturaly die.
I wait my death, but i try to do it good, without evil, with pure mind
It's my counsil to you too, Friend.
