1/2 live plays much worse than nl2 online
you were under rolled, the guy clearly saw that and was forcing you to decide if you wanted to risk going home after a single orbit - the stare down also seems to corroborate this - he was replaying the dirty harry are you feeling lucky punk monologue in his mind but with a cockney accent
that was a snap 4bet with the AQ but on the flop without a spade and as played it's a fold (or a jam)
You should also increase your standard raise from 3x if you want any chance at isolating like with the AA hand, he may have likely had T2 there
Don't bother playing live unless you can bring multiple max buyins, otherwise this is exactly what happens, you'll be forced to commit so much stack on unsure things and be playing scared
next time bring more money and honestly, have 2 drinks before you start, it'll help you relax as you were probably a little nervous playing live
