I'm not sure what do about this, i still have a few symptoms if PCS which are

brain fog - anxiety - dizzyness - fatigue - concentrating on things is still slightly difficult, i still forget some things and a few others i cant think of right now. The anxiety i think is getting a lot better, but im not entirely sure yet.

My parents are getting to the point where they cant really afford the house we live in anymore because our landlord is really screwin us on our rent.
They plan to move sometime soon im assuming, and with me still having PCS obviously getting up and lifting all the heavy objects in our house isnt a good idea at all and i really dont want to make things worse than they already are.

The problem is either my parents dont believe me when i say i feel terrible and explain some of my symptoms to them, or maybe they just think im trying to get out of things.
So when it comes time to move they might just think im making a big excuse so i dont have to do any of the work.
Every time i tell them i dont feel good they ask why and like the other day i told them about my sinus pressure and having really bad fatigue, and still being dizzy.
They shrugged that off and simply said "oh its probly just allergies"

Even after i've told them that i might have a sinus infection, literally all they said was "you might" and that was the end of that.
Incase you all are wondering Im 18 and my parents currently pay for my bills because im under their health insurance plan and im in no shape to get a job
i have Ulcerative colitis and now PCS, i dont even have an ID to get a job if i wanted to because they keep putting it off.

I have been wanting to go in and get a CT and MRI for a couple weeks now just to be safe and to reassure myself that i'm fine, and that the symptoms are really just PCS. And maybe have them refer me to someone to help with Anxiety.

but what can i really do or say to get my parents to take me without them saying "you're fine you're just stressing yourself out and still experiencing PCS symptoms" When on the other hand when it comes to something they want me to do, they think im fine and cured as if i never had a concussion..

Things are getting so frustrating, and im sure everyone here knows what i mean because i know all of you have been frustrated with PCS since the day it began.

Things are getting better i think, im still a bit concerned about heart palpitations.
Earlier today i started getting an anxiety attack over it because i was constantly thinking about it. At first i got REALLY fatigued and dizzy and started to panic a little, when it started i calmly stood up, sat down on my bed and took deep breaths and within a few minutes i didnt feel so bad but even now i still feel really dizzy and fatigued.

Should i maybe just chill out and continue to get rest? I am still a bit early in my recovery, I was diagnosed with PCS and a contusion on march 15th.
The reason im concerned about heart palpitations is because on my mothers side, her family has a history of heart problems. What should i do?
