At the beginning of AS, I was working hard working and motivated. However after doing my first ever practice essay in class in timed condition for Sociology (which I didn't take for GCSEs), I ended up getting an E. Ever since then, my Sociology teacher kept insisting I should drop out since I'm not good enough for the course, and made me feel dumb about choosing AS-Levels. I still stayed in the course thinking I should prove her label of me wrong, however I left my Revision a month before, due to feeling de-motivated. But ended up with a C (Unit 1-B & Unit-2-D, I'm thinking of retaking Unit 2). However in one course I got a B while in the other I got an E (I'm going to replace this AS).
I feel as though these results were also caused by my low self esteem. During my AS Levels, my "friends" used to keep emphasising that I was chubby and not as smart and pretty as my sister. I don't think I'm chubby or skinny since my BMI is&was normal, now that I think about it. Before I didn't care about what other people used to think of me, but I didn't neglect how I looked, since I still took care of how I looked. However, ever since those comments that those "friends" made, my self esteem went low. During the end of my AS I only found out they were using me just to get closer to my sister.
After all of this, my self esteem and motivation went really low. I also know I can't think like this any more, since I need to focus on pulling up my A-Level grades and move on.
How do I accept being ugly? and am I really dumb?
