Although we deal with probabilities and expectations, the actual results can deviate substantially from such expectations, particularly on a short-term basis.
You're not going to be different ... you're going to be the same as you've always been; with doubts, everlasting dissatisfaction with yourself, vain efforts to amend, and falls, and everlasting expectation, of a happiness which you won't get, and which isn't possible for you.
Here is the vicious circle: if you feel separate from your organic life, you feel driven to survive; survival -going on living- thus becomes a duty and also a drag because you are not fully with it; because it does not quite come up to expectations, you continue to hope that it will, to crave for more time, to feel driven all the more to go on.
