What would you do? #120 - Facing 3 flush river shove

Have you ever been scared of poker?  I'm somewhat frightened of the cards; the turn card, the river card, the flop, etc.  I think I'm broken as a poker player. For the last month and a half, the cards have totally gotten inside of my head. It seems as though whatever I do, it's the opposite of what I should have done. As a point of reference, without my luckbox cash in the BBT5, I would have had a HUGE loss of a month last month. Going from having never had a losing month to having a 20+ buy-in losing month is pretty tough to wrap my head around

I think I'm finally coming out of this terrible rut; I *KNOW* I'm playing far better than I was a month or so ago, though I'm still not making great reads. I'm seriously questioning myself constantly, because, yet again, my opponents always seem to be at the VERY TOP of their ranges.  EVERY TIME.  I had to quit playing Rush poker because of that very fact; if I have a "monster," then they have a bigger monster.  And when I have the nuts, they fold.  I wasn't getting paid when I had it, and I was certainly paying off when they had it.

Today's WWYD is an example of a misread (perhaps).  What is my problem here?  What do you think?

The Official DeucesCracked.com Hand History Converter

BTN: $31.50
SB: $50.00
BB: $70.20 - 9 / 7 / 11% steal / 1.2% 3bet / 4.7 aggression factor @ 282 hands
Hero (UTG): $95.30
UTG+1: $65.90
UTG+2: $60.40
MP1: $23.45
MP2: $54.30
CO: $31.90

Pre Flop: ($0.75) Hero is UTG with As Ad
Hero calls $0.50, 6 folds, SB calls $0.25, BB raises to $2, Hero raises to $7, 1 fold, BB calls $5
At this point, what range do you put a 9 / 7 who just called a limp / raise from UTG?

Flop: ($14.50) 3h Th 5c (2 players)
BB checks, Hero bets $7, BB calls $7
Probably too light here.  However, my thought is that I want to keep stringing BB along.  I don't put him on a draw at all and don't want to lose his business.  I'm kinda expecting a check / raise here and I'm happy to stack off with this flop.

Turn: ($28.50) Td (2 players)
BB checks, Hero bets $25, BB calls $25
He's being about as passive as a player can be.  The second Ten is a great card for me; only one combo of quads, unless he can't fold 55 or 33 pre-flop, which I doubt.  Obviously, he has QQ, KK.

River: ($78.50) 2h (2 players)
BB bets $31.20 all in, Hero ???
Is there even a question at this point?  I'm committed, right?

Hero calls $31.20


Final Pot: $140.90
BB shows Ah 8h (a flush, Ace high)
Hero mucks As Ad
BB wins $137.90
(Rake: $3.00)

So is this a top-of-the-range type hand for me, or am I terrible?  I really question myself after crap like this, because a month-and-a-half of this seems to be really getting to me.  I've been biting my tongue with posting hands like this, because I've been trying to be ignorant about it - saying to myself "standard cooler."  However, over 40K hands and 1.5 months - how many "standard coolers" can I have with it still being "standard?"  Am I doing something wrong?

It turns out, that for this session, despite this hand, I had my first "significant" win in a long time of 1.5 buy ins.  This is how poker messes with your head: I'm now considering a 1.5 buy in win as "significant."  It used to be that 1.5 buy ins was considered noise.
