struggling

hi to everyone, I have been reading everyone's post and thought I would post. I am new to the web site. I am currently taking the pre- reqs for nursing. I listened to the couselor at the community college where i am taking these classses, which are eng 102, algebra, phys 101, biology. At first I thought I could handle all of these classes at once, but being out of school for many years now I see this is not easy. I failed my first 2 biology tests and my first 2 algebra exams as well. I am so ashamed and disgusted that I am considering changing my major from nursing to something else. Though I want to become a nurse so much this is just hard. On top of that if I can't even get biology how will i maintain the rest of the sciences. I have no clue what to do, I registered for a&p I in jan now i don't know if that was a good idea. thanks everyone struggling
