I wanna thank everyone for your replies, they really helped. I suppose 4 rejections put me into panic mode. I reckon subconsciously I may have convinced myself I was gonna get in somewhere so suddenly being in this situation was a bit worrying- and ofcourse family pressure to go to uni didn't help.
Now I've had time for it to sink in, I've been able to think about it logically. It seems pretty obvious that a gap year really is the most rational thing to do. I'm working to get a placement at the local hospital.
I also wanna thank Sidsingh for recommending Ovidius university. It really is an impressive medical school, and I've decided to keep it as my backup. I spoke to the university and they've said as long as I send the right paperwork next year, they'll be happy to take me, so if I'm really unlucky next year and can't get in anywhere here, atleast I'll definitely be going to medical school somewhere.
To anyone else who might stumble onto this thread in the same situation, it's scary at first. The natural instinct is to get in somewhere and be 'safe.' But after thinking about it, the sensible thing to do is work out where you went wrong (in my case ukcat) find a way to fix it, and try again. Abroad it backup.
Oh and just for the record, I didn't want to go abroad because I thought it was an easier option. I don't think anyone can deny that every year there are more than suitable medical applicants with all the desired qualities who are unable to get into medicine first time, simply because there aren't enough places. Out of those people, some will decide to choose a different career. The ones who are really committed will take a gap year or go abroad, because some countries will have places international students- so there's still a chance for us. I don't think either options are easy. It's just that a gap year is the better choice as there's still a chance I could get into a british medical school. If things don't work out, then I can go abroad so I'll still be a doctor.
