36M - Feeling Irrelevant, Old, and Bored. Anyone Else?

I’m 36, married, working in IT, and lately, I’ve been feeling irrelevant, old, and bored. In the warmer months, I’d keep myself busy riding my bike, gardening, or doing projects around the house, but winter has hit, and I feel stuck. My weekends have been reduced to watching movies and scrolling endlessly, which honestly isn’t cutting it.

I’m a huge introvert, and I haven’t managed to make new friends in the last 10 years. Between work and just life happening, it feels like socializing has gotten harder, and I often don’t even know where to start. I know a lot of this is on me—I’ve been in a bit of a rut and need to figure out how to change things, but I don’t know where to start.

I’m curious: does anyone else in their 30s feel this way? How do you deal with these feelings of boredom and irrelevance? Have you found hobbies, routines, or ways to connect with people that made a difference? Any tips for someone introverted like me?
