As I have already said, I'm in a similar-ish postition, in that I have an animal related degree and don't know what to do or where to go with it. I know that doesn't help the OP with their problem, but there are lots of people out there with the same issues.
The points TAD has made are fair enough in that, yes, ideally it is something that would/should be thought about before starting another degree. I can only talk for my situation, but unfortunately, through bad planning on my part, bad advice from several sources, I made what with hindsight was probably the wrong decision. I got onto my degree through clearing, when I realised I hadn't got the right a-level grades. I took advice from the uni, my college and connexions, all said that would be the best way to get onto a vet course with my a level grades. They all suggested it would be easier to get on that way, I wouldn't have a problem getting a place provided I got a 2:1 or a 1st etc. With hindsight, it was bad advice, but at the time I trusted careers advisors to know what they were on about
The uni quoted jobs that people had got into with this degree, again, me being naive, I didn't realise that they were 'one offs'. That they were the few select people from the past several years who had managed to get good jobs after uni, by luck, by knowing the right people in the right places etc.
It sounds like I am moaning I know. And apologies for taking this thread off track. Everyone is different, in my case I think I made the wrong decision. It is my fault for not finding everything out fully to start with. I thought I had at the time, but I believed the wrong people. It is now a case of trying to make the best out of a poor situation.
Try to go easy on the criticism of people for having ending up in a situation they didn't foresee.
