Yeah, you're def beat. Good fold. Could consider a donk block bet then fold to a raise -- trips aren't going to raise there.

not my stakes, but I try to show you my point of view.
First of all no CB is a pretty big mistake in my opinion - but you probably know that (cbetting on tp+ isn't the best idea here).
2nd you can consider x/r OTT if villain is really aggressive, it's pretty interesting line in my opinion.
as played, x/mr OTR is a decent play, shoving might make him fold his trips, but you should probably count how many flush combos he has in his range and how many of them he bet/calls OTR and than count ev your raise sizing.
If he shoves vs your x/mr it's a easy fold imo.

.ps I dont like donkbetting OTR. There's no much sense to do that, anyway he's going to bet his trips+ OTR and bluffs with some frequency trying to fold your 2nd pairs, so donkbetting only cut off his range from bluff.
Medium value range obviously dont bet otr and dont call your DB.
