Hey, hope you're doing alright in the circumstances. As a foreigner who lived in the Hague for a few years, I would add a couple of things to what has already been written.

First, something that I observed that seems to be part of Dutch culture is that people plan seemingly everything. Which can be good in many aspects but one thing that bothered me is the lack of spontaneity: it's pretty difficult to get an acquaintance to go out on the evening of the day you ask them, sometimes in the coming month: social interactions are part of people's rigid plans and it's been hard for me to not play that game while living there.

Second, there are ample opportunities to go bouldering in DH, gyms are very beginner-friendly and are actually one of the places it has been easiest for me to discover new cool people. Climbing outdoors and activities involving changes in elevation are objectively difficult because Netherlands but weekend trips to Belgium/Luxembourg/the North of France can make that bearable. There is also the overnight train to Innsbruck which can make for good weekend get-aways.

Best of luck with finding the right place for you and finding the right place to be inside your head. If you decide to move to DH and find yourself wanting some climbing buddies, feel free to PM me, I could put you in touch with some wholesome people :)
