Call Happy...Tell Me to Stop

[Mercman572]

I make this play WAY to often, its my only noticeable leak right now but its a bad one. I can't help calling checkminraises even though I tell myself to fold as I am calling. I coax myself into calling saying "He's a donk I could have him by kicker, I am getting good pot odds on a call any way and the implied odds are ridiculous if I hit"

This hand does not help:

I convince myself into calling thinking I am getting 4-1 on my money and he either has 9/10 or TPGK since I have been continue betting. To help me fix this can someone please tell me:
1. A donk will almost NEVER check minraise
2. what are my odds of hitting my other card or seeing runner runner flush (I know they are not good but would help if I had the actual number figure)
3. This is bad poker, dump these hands and you'll save money
