I need advice about my education and life. I feel stuck. Can you give me some opinion?

I am currently in first year university. My marks aren't that great considering the fact that the highest mark I got on my midterm was only 68 and my lowest mark 58. And yes, I have heard that during your first year your marks drop down a lot compared to your highschool grades. I have went to talk to my TAs and my profs and even went to see a study counselor to improve my grades. I am currently in the process of switching up my study method and I don't know if it'll work, but it is better than not trying. I really really want to major in honours psychology. To get into BA honours psychology next year, I need at least an average of 75 and I am no where near that. I am really scared that if I don't get in, I cannot go into graduate school. I am also worried that even if I do graduate with an honours BA psychology degree, there aren't many high salary jobs out there. I really want to earn enough money to raise my parents (because they are getting old and I don't want them to work..my parents had a hard life) and to support my two younger sisters going to university in the next few years. Sometimes I wonder if psychology is really the right road to go. Because in psychology, you need to have excellent communication and writing skills. I don't have any of those skills...(i suck at communicating with people because I realized recently I have social anxiety..i developed this from something that happened in childhood...im trying to get rid of it...seeing a counselor for that too right now) I am trying to improve my writing skills by reading and writing frequently whenever I have time. But still...it'll take a while. Whenever I think about this problem, I start to wonder why am I not good at math and science? I took math in Grade 12 and I tried my BEST, I worked my ass off for at least a 75 but in the end, I finished with a 61. I even had a math tutor and a friend that was a math genius to help me. But I still didn't improve. In science, I always get mid 70s. That's why I chose to pursue something that is not related to science and math. I really enjoy psychology though. I really do. It's just that there aren't many job opportunities out there for BAs.....
sigh~~sorry for my huge story/rant. I don't know what to do....what would you do if you were in my position?
