Feeling so low...

Feeling so low in my life in the last few days until today. Don't know how long it will last this time around and it looks like that I don't want the feeling to stop. Sometime, it might be better if I just let my feeling to take its space in me...it came uninvited and let it go by itself. I don't feel like to go against it.
I'm not the one who likes to entertain this type of negative feelings to have any sort of control in my day or any part of my life but this time I feel very much different.
Knowing this will give some impact in everything else that I do...I don't feel having the strength to fight my frustration, anger and all kind of similar feelings at this moment.
Why???? I don't have the courage to say it even to myself but deep in me...I feel it so much! It make me feel useless and all what I did have no meaning at all. Feeling myself so bad although I know that I am not too good anyway. I'm just a normal person, a man, a husband, a father, a son and a father with a normal desire to do the best in his life.
what the hell I'm writing here?!!!
Yeahhhh! My brain is in a mess now...hope?!!! better let it be like this for a while...I just want to let the natural "evil" feeling enjoying its moment now...who will pay?!!! I believe people deserve what they deserve...So do I!
