Glad you're feeling better Abominator.
Remember, success is not in never falling but in always rising again. You screwed up, but hopefully you won't allow this to happen again. Next time you'll put forth a better effort in your classes, and if you have any questions on the material, you will seek the necessary help. Feeling sorry for yourself won't do yourself any good in these cases. But cheer up this it's not the end of the world; in fact the first semester is usually people's worst as they enter there first year of college. Most students aren't used to the kind of freedom college gives them; by this I mean everything isn't mandatory as it was in high school. So it's safe to say you'll take more chances than you did with high school. You have to remain consistent; meaning you have to put the same amount of effort from start to finish. It's gonna require some sacrifice, but you can do it.
Good luck, and remember it is not in success where a true character is revealed, but in failure.
Been getting pains in my chest lately, getting them checked out by a doctor
Hope it isn't anything serious. How long have you been feeling these pains?
