<human>: Yep so, I'm getting pretty stuck in college. I'm an ecological Biology major taking the advanced Chemistry series this quarter and Calculus the next. They're pretty tough, and my very poor study habits are leaving me very behind in class. Unfortunately, I also struggle with anxiety & ADD. 

In high school I got through with good grades with hardly any work, & once I got to college that changed hardcore. I found myself failing & dropping classes, after some hard work and easy classes I finally got off academic probation. Procrastination is a HUUUUGE issue for me (reddit!). In general I am a smart person, but I learn some things at a slightly slower pace than others. There's also the recurring cycle where I won't go to class because I'm behind, then won't study and will get more behind, etc until I haven't been in a week. It just stresses me out so much that I avoid it.

So, has anyone struggled with something like this before? In any of these categories? If yes, how did you overcome it? ANY help is greatly appreciated. Thank you in advance.

And before anyone tells me to just drop out or switch majors, no fuckin way. I've wanted to be a biologist for as long as I can remember & I'll die trying (or in debt) before I give up.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I am poopy & fail hard classes. Struggling with ADD, anxiety, & poor study habits. How do I get good grades?
