<human>: Summarize the given text in a few sentences.

So, I've been getting busier and busier recently, and I feel I'm drifting apart from my best friends. It's killing me, I love these guys, but I've got obligations and I don't get to see them often at all!

On a weekly basis I've the following obligations:

Work late at least twice a week, see my girlfriend at least twice a week, and at least once at the weekend. Visit my ill grandma to make/have dinner with her (usually after work on a Wednesday).

So assuming I only see my girlfriend twice, and I don't get asked to work late more than usual, that leaves me with 1 evening and 1 day of the weekend. I don't even get any time to myself these days. I used to love going and doing things on my own.

I have 4 distinct social circles, who for the most part don't interact, and I'm struggling to slot everyone in. My girlfriend wants me to make more time for her too, but I feel like there's not enough time in the week as it is :(

Yesterday, for example, I was asked when I can come hang out by one group, and I looked at my diary, and said in 3 weeks time I've got an evening after work. The only reply I got was "are you serious?"
<bot>: really busy, people upset that I don't hang out any more. How can I make more time or help them understand that I'm ridiculously busy, but I still love them dearly.
