Hello there @Joncorry, welcome to the forum from one survivor of Myeloproliferative neoplasms ('MPN') to another. I’m really so glad you found us here, and I see dear @DuncanB has already greeted you with his kindly wisdom—do take Duncan’s advice!
You know, so much of what you’ve shared is spot-on and very familiar to me, having been diagnosed with a closely related type of myeloid blood cancer called Polycythaemia vera ('PV') in 2023. I went from being active and healthy to suddenly needing chemotherapy and phlebotomy, and your description of feeling such strong emotions has been hard for me too.
If I might offer my experience that living with Myeloproliferative neoplasms ('Myeloproliferative neoplasms ('MPN')') can also quickly become rather routine once treatments stabilise things, I hope that gives you a little hope that this difficult phase after diagnosis will likely pass. I find it kind of incredible that my blood cell numbers are all normal and I can function healthily while living with blood cancer, all thanks to taking my daily medicines working as intended! Amazing science 
For now, let yourself feel it all I’d say as it’s a lot to take in, to say the least. While you take in this big news and the medical language and information, I’d say let this all sink in and take your time. What could be more emotional than a cancer diagnosis?! I hope you have loved ones with whom you can share how you really feel.
After diagnosis for me it felt a bit like grief for my former self, and like other types of loss it gradually became a bit less raw as time passed and I processed my anger and sadness about it all. Learning more about living with Myeloproliferative neoplasms ('MPN') helped a lot. Finding others on the forum living well with Myeloproliferative neoplasms ('MPN') also gives me a lovely boost to this day, and you’ll soon see there are many of us around the forum with these rare blood disorders. It’s not so lonely when we can reach out to others right here!
I’ll share the great Blood Cancer UK information about Myelofibrosis ('MF' or 'PMF') here for your reference: Myelofibrosis (MF) | Blood Cancer UK
Here is MPNVoice that specialises in Myeloproliferative neoplasms ('MPN'), and they also hold conferences (“patients’ forums”) which may be of interest to you as an educator: https://www.mpnvoice.org.uk
I think you’re wise to play it by ear for now in terms of work as our energy levels can indeed be affected by living with Myeloproliferative neoplasms ('MPN'). Something like 80 % of people with blood cancer unfortunately experience cancer-related fatigue (CRF) so you might find the following useful for finding ways to improve your energy level: Fatigue | Blood Cancer UK and Tiredness (fatigue) and cancer | Macmillan Cancer Support
Dear @DuncanB has shared the contact information for the lovely Blood Cancer UK nurses and I would urge you to give them a free call with any medical queries or for further resources on 0808 2080 888.
Hope that helps a little to get you settled into the forum, please know you are not alone with your diagnosis and any treatments you may be offered, and please do reach out to others here. We’re a friendly bunch, even through the fatigue!
Keep us posted about how you get on please @Joncorry, I’ll keep an eye out for your posts.
