New to the UK, and struggling with winter. How does everybody else do it!?

I'm finding myself not going out much, almost like stuck inside, not finding purpose to go for walks outside since there's not really much to see more than houses... Im sick of the tv, I read too much already and my mind goes to alcohol but I dont really want to. I try to be productive but this boredom and grey days are really taking a toll on me T.T I paint. I play xbox. I do exercise. Yoga. But Im finding myself always looking for the "what's next" is this depression? Anxiety? Is there anyone else feeling like this?
