Ouch, sorry
I'll try giving advice, not sure if it'll be any good.
Hand 1: Would it be safe to assume 25NL full ring players aren't raising with draws? Unless you've got several reads that a particular player does so.
Hand 2: A tough spot, but I think most players at 25NL full ring aren't going all-in pre-flop without KK+. It might be a good assumption to make when facing 3bets, unless you have several reads on a player he goes in with worse.
Hand 3: Shove turn? He's clearly not worried by the flush. Although in the long run, it might be better just to call turn and get value out of worse hands which bet the river (i.e. sets and 2pairs).
Brutal river and tough to find a fold. General rule of thumb which might help you in the future: when a player is betting 80-90% of his stack on the river, he's got a huge hand 100% of the time. They think it's more likely you'll call that bet than call an all-in bet.
edit: should have said 4bets, not 3bets. yeah 4bets are even more likely to be KK+. some players may only 4bet with AA.
