Moved to Bellevue recently. Why does it feel so lonely and desolate here?

I graduated recently (was in NYC) and moved to Bellevue (a suburban house near Crossroads) around 3 months ago.

I earn very well, got a great car, house, stress-free job, lots of free time, stability, calmness. However I feel some extent of sadness, purpose-less-ness, and a sense of loneliness that has constantly been creeping in.

I’m a hyper-independent person and have always enjoyed doing everything Solo. I love mountaineering, hiking and outdoors, and I know the PNW is a great place to be for that. However lately I’ve even lost interest in making the effort to go hiking. I recently flew planes in Alaska and now even the PNW has started feeling tame compared to that.

I have many other hobbies like music, art, dance etc. that I want to restore and get busy with here since I have the time, but I don’t know why I just don’t feel like it. I feel like I need some friends or a girlfriend to feel something. Everything feels meaningless, and I feel like I should start a family or something to feel alive and busy.

Maybe this is more of a mental health concern, or just a coming-of-age thing (I’m late 20s), or just a result of gaining stability and calmness for the first time in life, and not knowing what to do with it now. But I feel like Bellevue being so desolate and lonely with no way to make friends and meet people, is a factor too.

I need some guidance.
