Medical School Panic

So, in one month I'll be finishing my 2nd year.  Excellent and I'm finally healthy enough and my ankle seems stable enough (touch wood!) to begin my volunteering, which is amazing.  I also have the shadowing sorted for the summer, alongside the project I've been working on which has been amazing, but I can't help feeling my application isn't going to be strong enough for this year.  I did a practice UKCAT test yesterday for the first time (I didn't even know what was involved) and it was ok I suppose for a first attempt, aside from the numerical section which was absolutely appalling, which does not bode well for me at all.  I really didn't want to rely on the GAMSAT too much as it is such a beast I wanted 2 UKCAT Unis and 2 GAMSAT Unis and now I'm worried that I'm going to have to go for 4 GAMSAT unis.  

I have absolutely no idea how this is all going to pan out, I had everything planned to the nth degree and then I messed it all up by getting injured.  Completely my fault, but it isn't going to make me feel great when I have to take yet another year to apply again if I don't get in this time.  I'm a mature student (I'm still the right side of 30 but still!) and I just feel frustrated. I'm seeing on forums that people who are quite honestly fantastic candidates getting rejected from all 4 choices, even with high scores, high academic grades etc. 

If people who are:
a) Younger than me
b) Have better academic credentials than me
c) Have higher GAMSAT/UKCAT scores than I can ever hope for
d) Have more voluntary work experience than me
Aren't getting offers, what am I supposed to do?  I just hope that I get one offer, I don't mind where, I really truly don't, I'll be happy with any of the 6 places I want to apply to (I haven't narrowed it down yet, open day season is upon us!) were kind enough to offer me a place I'd be over the moon.  I can't quite get my head around people being offered places and then saying that they're not sure they're going to take them as it wasn't their "first choice"... *DON'T APPLY TO A UNI UNLESS YOU'RE HAPPY TO TAKE THE PLACE*. 

Anyway, I'm going to stop ranting, just having a moment of complete and utter blind panic! I'm going to go and revise, because one thing is for sure, I'm not going anywhere unless I pass my degree!  Thanks for reading.
