Help me with these hands. I'm a bonafide donk

[C.R.E.A.M.]

Seriously, I don't know what's going on. My first 1000 SNGs at the 22s I had a 16% ROI and thought I was the [censored]. I figured by my next 1000, I'd be playing so good I'd be sitting at a 20% ROI. Well, over my latest 750 tourneys I'm running at 3% ROI, and my latest 300 has me at -3% ROI! I can't figure out what is happening to my play. I think one of my big leaks might be donking off my stack with hands like TPTK and not listening to people when they tell me they have me beat. Ok, enough ranting, here's some hands I probably donked up that I'd like comments on:

1. I'm guessing my flop attempt to buy the pot is terrible. Is PF raise terrible too? But I had no idea what this guy has buy the way he called and made weird 1/5 pot size bets.

2. I feel like I'm constantly getting stacked with top pair, top kicker, or top pair good kicker. Constantly. If I'm not willing to get a lot of chips in with it though, isn't it just a glorified 72o?

3. Am I weak-tight or is letting go of AA to a dangerous looking flop to such a small bet correct?
