Parents are trying to help and I can't accept it?

I'm F30 and my parents only recently started to care about fibro (after a 15 years of telling me it's my fault for beign lazy and depressed)

Lately the fibro symptoms have been blending with some MS symptoms. Pain was so intense I lost conciousness in public transit. ER Dr gave me a referral in neuro to make sure it's not MS.

After that incident, it suddenly clicked with my parents that I wasn't "blowing things out of proportion again".

They started to read about fibro. That's great! I should be grateful.

But then proceed to "remind" me I need to move more, do more sports and eat clean. Now that they did some research they know more than I do, surely.

I left my parents' house at 17 : they have no idea of what my daily life is. I am already doing my fucking best to survive.

Instead of being happy they finally try and understand, I'm bitter and angry. I don't like it at all. I don't want to dwelve into negativity, but it was so hard to smile and say thanks when I got a message of an artistic representation of fibro pain. My first reaction was to feel insulted. I wanted to say I don't give two fuck about how this artist feels, I want to focus on MY pain and fatigue.

Thanks for reading. I needed to vent, I needed to be ungtateful out loud for a moment. I will calm down soon, but right now it's hard.
