My best friend in college was my math prof (now if that isn't a mental health issue I don't know what is!). She had the following quote from Aristotle on her door:

"The good Christian should beware the mathematician and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of hell." -

on a more serious note...

You may want to get tested for a learning disability in math. I was lucky in college to have the best math professor anyone could ever ask for. She taught modern math with giant home baked chocolate chip cookies, statistics with M&N's... All of it with great kindness and patience. Wish I could overnight her to you. If someone was trying as hard as you are in one of her classes she wouldn't let them fail. She wouldn't stop trying until she knew why it was so hard for you AND how she could make it easier. I didn't take her college algebra class, she wouldn't let me. Said it was the hardest of her classes for students to get. She knew it would overwhelm me if I couldn't understand it. Is there another math class you can take with a different type of math? I took modern math first because I was math phobic but with the profs help I went on to take 2 other math classes with her as electives! Not all math is the same. I do best in geometry and statistics and even like math now.
Anyway... if I can help feel free to PM me. If I understand it I am good at coming up with different ways to teach it.
