A part of myself

I'm a person who like to keep thinking a lot, not matter when, what or where....I will think a lot once I start to think.

Sometimes,I'll ask myself why I like to think such many, it only make me feel down and suffer.Sadly, I cant change anythings because it's already one of my bad attitude. For me," think a lot" is just like my leg, I will feel weird without my leg.Anyone understand me ? 

Not matter what, I hope it wont change anythings in my life not matter is family, friendship or love. Please be with me.
