What I was saying in the beginning of this image was that there are just going to be people who just don't get your illness. And that is fine. It doesn't in any way invalidate your illness. We do not need to prove it to them. We have that illness. We don't need to definitively prove it to any naysayers like it is on Us to show the evidence we are in fact sick.
AND... that is where the second part comes in. Because who needs those people in our lives anyway? Dealing with all that argumentation and doubt? None of this changes the fact you have an illness, but might change the amount of time you spend with that person. But, whatevs, you never liked that douche nozzle anyway.
We really don't have to get drawn into these arguments. Someone does not believe you are as ill as you say, as chronic as you say, or have the right diagnosis.... that is on them and whatever reason they have for doubting medical professionals. It is not on you, to have to validate its existence to them. So random person A doesn't get it? Random person A can walk in and out of your life just never knowing the answer.
Frankly you could say this for every one in your life that doubts your pain. I have it. I don't need to validate its existence to you, just because you cannot see it, feel it, understand it yourself therefore doubt it. It is enough I know it and will treat and manage it.
We really do want loved ones to know and understand our chronic illness though. The more understanding they have of how our illnesses work the better caretakers they are when we need them. The better assistance they are when we need them. If a spouse does not get it, you want to try an educate them. If they refuse to read up on it, listen to you or your doctor... then that can lead to serious relationship hardship and coping.
