I am in a point in my life where I either react and change myself, or I won't be able to endure this for long. My heart obviously says "just go, there's nothing for you here", but to be honest with myself I am timidly trying to correct some of the bad habits I have. That way, I will at least be able to tell myself "I tried".
At that point, there's like a "reverse immune system" that comes in place: when I am able to open myself with someone, in 2-3 days I'll be a complete asshole to that person, so it goes away.
If I try to take a good habit, at the first occasion I destroy all the work I've done up until then.
And so on.
I am aware that I am my worst and only enemy. The world doesn't hate me: it's indifferent. But I am doing all this to myself, and sadly I can't get away from myself if not with the most definitive of solutions.
So yes, I am destroying what's left of my life and of my hopes, I see it happening and until now I am not able to stop myself from doing it.
