No, I don't think you sound mean, just tired and frustrated. From the history that you have provided you have every right to be!
I sympathize with you and hope that you will get some relief very soon. I'm sorry that I can't offer anything more to you than support and understanding. I am new to this amazing and horrifying journey and all I can hope for myself is that my story will not be as difficult as yours but am starting to understand that most of my life long symptoms are likely related to parasites and their debilitating effects.
If you have the energy can you tell us what you have done to boost your immune system?
What do you other guys think? Any helpful suggestions for this poor guy?
Linenup would recommend testing at MM. Have you done that yet? Edit....I just read where you did ask about testing and received conflicting answers. It's all so flippin' confusing, eh?
BTW - it's interesting that the most affected by these silent but deadly monsters are so afraid of being labeled crazed or imagining their problems. From what I've seen, if you're not crazy at the start of this horrid journey, you will be!
