If you want to say ...

Thank you for this post.

I have been guilty of saying most of these negative things. I can be as awkward as it gets at times...

This post frustrates me, it should be backwards. If you want to say sorry, say thank you. Show people that you appreciate that they're helping you, or that they're there for you. Don't make people say feel bad for saying sorry, nor tell them what to say ( if they were cognitively wanting to say 'thank you' they'd say it).
