I’m sorry you have to deal with all this negativity. I have so much faith in you that I am laughing at these people on your behalf. (not sending them negative comments, but having an attitude not of contempt but of winning.) You’re winning.
Your feelings and reactions are your own and fully legit of course. Just wanted you to know you have someone with this kind of attitude on your side. And many others here no doubt.
I don’t know what you plan for a course. But that sounds like just about the most exciting thing ever. Thank you for giving me something to anticipate.
