You will.

You know you want to prove your worth, so do it. Stop being a ****ing wuss and stop moping and hanging on to everything like a whiny little boy. Get on with life, deal with your challenges, and solve your issues systematically. You used to be the most rational person you thought you knew, never giving in to emotions. It's time you picked yourself up from this mess and do what is right. You know you need to do well this semester. There is still a chance, but don't beg, don't hope, don't wish, don't wait. Work for it, and in the mean time do everything you need to do so you can get to a position where you can start to fix things. You know things will be different come next year, so you better be here next year to witness this change. Take it in your stride and work towards your goals.

Quit whining and get moving.
