I Wish I Knew Then What I Know Now

I feel bad for being completely dependent on my female friend who supported me in my hard times during College. She was a complete extrovert while I was totally the opposite.
I wish I had the will to stand up on my own and take up any crap thrown at me and still ignore and move forward back then. I wasn't completely late though. We're still friends but the closeness passes you know.
Right now I'm just another clingy friend who cannot handle things on my own even though I've become better than I was.
