When its love you'll know brother, though you won't know why. Spent my whole life searching for the why and still havent found it.

This is extremely well written! You have flawless rhyming and great word choice.
I can relate to this in many ways, and understand the quarrels that haunt one's mind when it comes to loneliness. It can be discouraging and even more disheartening.
But remember this- our imperfections and quirks are what make us unique and who we are. Don't be ashamed of that...because one day someone will come along who will love everything about you...imperfections, quirks, and all :)
Be yourself. Love yourself. Accept yourself fully as who you are- and watch the universe work its magic.
Much love and peace to you, and well done on a fantastic write!

And welcome to the site! :)
