Another A level??

Things dont seem as simple and easy as i first thought..
It seems like I'm going to prepare to live another 3 years of A level life which Im a little reluctant.. ):
Its tough, I admit. Its overwhelming, I feel. But everyone seems alright and ok.
I have a united class, friends that will help me in Bio stuff whenever I need. But sooo long I didnt have feeling of lost during lecture.. But now, i did. I was totally lost during a 3hour straight of Human Physiology.. I was also lost during Mobility lecture.. Mobility wasnt that 'easy and interesting' as i thought. Yes it was but, it involves more than just physical stuff of moving or transferring a patient.. It involves lots and lots of processes and goal setting and stuff.. And lots of assessments.. be it clinical or practical..
I know Im trying to avoid being uncomfortable to step out of my 'comfortable' zone.. Trying to take off my study responsibility now.. I know i know, i know im not supposed to but i still can settle down to study.. there are alot of factors contribute to this uncertainty..
I think that i have all the things that an OT needs, like say compassion, empathy towards patient, positive attitude and just everything lar.. What i really lack is confidence. Confidence in study and do okay in academic. Where do i search for confidence? how am i supposed to be qualified or even call myself a future OT when I myself lack confidence? am i supposed to look for an OT now to instill my confidence level? hahaa
Anyway, OT does thing with a purpose, increase the SOL of ppl, unlike Physio.. haha thts what Charmaine my Mobility lecturer said.
Take care ppl!
