LLM Experience and workload

This question is targeted towards those who have completed LLMs. It isn't the usual 'should I do an LLM?' question - I'm already fairly sure I want to do it because I'm genuinely interested in taking my studies further.

The question is more related to the experience of the LLM itself. I was pretty lazy during undergrad and I didn't make the most of the opportunities. I would like to try my hardest for once with my studies whilst simultaneously making the most of societies and going out with friends etc.

Did you find it a lot more lonely than undergrad? I've heard different opinions from different masters - MSc graduates often say how tough it was whereas others say it wasn't much different to undergrad.

I know it's only a year so I wouldn't build as close friendships, but my question is basically about whether it's a year of independence and constant studying or whether I can also make the most of the social aspects and opportunities that I didn't go for at undergrad.
