I’m no expert but wanted to respond becos it’s late - and hate the thought of someone worrying about a vac scheme late at night.
Firstly, can you contact your normal go-to (doctor, parent or friend)? It may be easier to chat this all through with someone who has helped before.
Then maybe take the pressure off yourself, these weeks do tend to be back-to-back, but I imagine a lot of the stress is the pressure vac schemes tend to put on themselves to do perfect work.
Maybe you can reframe the week i.e, instead of looking at it like an assessment, just think of it as an experience that you are doing to find out more about the legal industry and to build your CV. So don’t put any pressure on the final outcome.
Remember, most people at law firms are super busy (and we are all slighly self obsessed) so others are probably not examining you as much as you think. I wouldn’t worry about them ‘seeing’ your struggles, they have their own worries and see loads of open day/VS students. They are probably not that focused on you.
Obviously you need to do what’s best for you and you’ll know that. But if you think you can give it a second shot with a different mindset and take the pressure off yourself - you may even enjoy it. Equally, a vac scheme is a two way street, after the scheme you may decide it’s not the type of law firm you want to work in.
And remember, you must be a pretty good candidate to have gotten a vac scheme - they don’t come about easily
In terms of practical tips, if it’s too much socialising, maybe skip the after-works drinks/dinners and take a walk around the block at lunch time, to make sure you’re getting some recoup time.
