To be a Barrister, or Not to be?

I'm going to an open day for the BPP Law school in one of the London centres this saturday, so i'll be writing up a post on that soon afterwards. I'm ever so excited, and hopefully going there will reinforce the reasons why I wanted to go into law in the first place, and show a bit of an insight as to what I'll expect after my degree.

 The trouble is, I still don't which type of lawyer I want to be yet. I have at least three years from now, but I know that'll go swiftly. I know that whichever type of lawyer I become, I shall definitely go into Human rights law, as that interests me most (I wanted to do criminal but my mum opposes.) but I just don't know which type of lawyer. I'd love to be a barrister (I can be quite argumentative and would love to verbally defend) but I'm scared It'd be too competitive and expensive and I know that my skills can't guarantee me the job.

I know becoming a solicitor would also be pricey and competitive, but I feel it may be somewhat more manageable than going into the Bar. I already fear that my ethnicity, poorer background and gender are set backs, and going to uni where a lot of people seem smarter than me doesn't ease those insecurities. Hopefully all shall work out in by the time I reach that hurdle eh?
