So I’ve been wanted to read some good horror psychological stuff. Maybe something simila...

I haven't read Sweet Home so I can't compare but the description matches :

Warehouse : http://www.mangago.zone/read-manga/warehouse/

Killing stalking : http://www.mangago.zone/read-manga/killing_stalking/?av=2

Obey me : http://www.mangago.zone/read-manga/obey_me/

Sorry if you've read some of them (I guess everyone has read killing stlaking tho)

Bastard (if you haven't read it already, same author as Sweet Home)
Superior Day
World of Law and Order
Infectee
Dead Days
Hive

i don't have any good ones, but escape room is a thriller and will freak you tf out but it's still very good. i feel like it has similar vibes to what you're looking for, but definitely less on the psychological portion. still give it a try.

hello is escape room in mangago? i can't find it..

you can actually read escape room for free on webtoons
