Change in circumstances after winning tribunal

I recently won my tribunal and was awarded standard for both sections. I provided a lot of information about changes to my health just before the tribunal, which they advised they didn't consider and only based their decision on my circumstances and evidence provided nearly 4 years ago.

I contacted DWP and they sent me a change in circumstances form and said I could just put a covering letter to ask them to refer to the information I provided recently and just note anything that has happened since.

I've done that, but I did not say that the information and evidence I submitted a few months ago was not considered by the tribunal. It just sounded like I'm saying my circumstances have changed since the tribunal.

I've got myself into a complete state about this today, worrying I didn't make this clear and they'll reopen my whole claim and I'll have to go through the entire process again. I've been sick three times this morning just worrying and wishing I had just left it.

My conditions and circumstances the tribunal awarded on have not changed, with one worsening and linking to a long term progressive condition I was diagnosed with last year. But I'm am just so worried my cover letter looks like I'm saying the tribunal considered everything and here's a couple of minor updates from the last 2 months.

Has anyone got any advice, because I'm sat here by myself so stressed I've been sick and can't think about anything else. What is the process after submitting a change in circumstances form? Should I try phoning them Monday to say I submitted the form because some of my conditions and my health have deteriorated since 2023? Therefore were not considered in the tribunal.
