Preventing or allowing myself a relapse?

I quit smoking 6 month ago when i moved country, after being a daily user for 10 years. I had a pretty rough relationship with the stuff, as much as i loved it and it was like a comfort for me, i was fully dependant on it and it was making me anxious/paranoid in certain situations, depressed that i couldn't stop doing it, felt like it ran my life etc etc.

I moved and it was actually incredibly easy for me despite being genuinely scared to quit (Had tried many many times before), i was so busy with the move, fixing up the house, finding a job, attending interviews yadda yadda. Fast forward to now, things have slowed down a lot, i don't have a lot going on other than work, i haven't made a single friend here yet due to social anxiety (Other than work friends that are completely different ages/personalities to me) so i'm not going out socialising and the thought of having a smoke again, especially with it being the holidays and not having much to do, is almost overwhelming.

The hardest part for me is always late evening like right now when posting this, i'm into video games & movies but don't really have anything else to keep me busy at night, which is when i would usually have a vape or joint previously. I'm extremely unsure of how to proceed. On the one hand i'm saying to myself. it's fine if you want to have a vape, it's the holidays, you've not got anything going on, you've successfully moved country, something you wanted to do for years but was too scared to do before so congratulate yourself and chill.

But on the other hand i don't want to cancel out 6 months of progress, feel like i've failed, get back into smoking properly again (Was only thinking to allow myself over the christmas break). Has anyone got any advice or thoughts? I'd really appreciate it, sorry for the wall of text

Happy holidays everyone
