You've come to a wonderful place, welcome to GW2!

I suggest you should take a look at YouTube channels by "Mukluk" and "MightyTeaPot" and similar YouTubers, they have a bunch of guides and informative stuff on their channel, especially Mukluk
Here's an example of a beginner guide if you want to take a look:

For some more technical things you might want to look at guides such as this:

And finally, Guild Wars 2 has their own Wikipedia page where you can find all the info in an official capacity:
https://wiki.guildwars2.com/wiki/Main_Page

You can use the Wiki page even from within the game, just type this into chat when you're in-game:
/wiki (name)
Instead of (name) you type the item or whatever you’re looking for ofc

Hope this helps, enjoy!

i've recently decided to take a break from one of my most played games destiny 2 because the game has brought me a great deal of anger and disappointment. so now i'm looking to find a replacement for destiny 2 and my search has brought me to this wonderful game. Is there any tips and guides that the GW2 community would like to give me as a new player of GW2?

If you end up not liking GW2 (great game imho), you can always play Warframe (also great game imho). The latter is more like Destiny 2.
