Feels like I’m currently in no mans land

On the 31st March I was admitted to hospital with shortness of breath - within being there for less than 8 hours I had a CT scan where they discovered a growth on my heart, along with changes to my liver and spine. I have have a biopsy on my liver, along with MRI of my heart. My case has been referred to a specialist sarcoma team. I was in hospital for 16 days on a lung ward while they removed the liquid, I have made it home which is allowing me to process everything - I am devastated! But at the moment feel lost - what does this mean, when will I know more l. I have kids at the moment they know I am more ill than we first though - but I don’t know how I deal with this what are the next steps etc I feel like I am in no man’s land!
