My heartfelt condolences, my dear. My DH died last November and his funeral (a Requiem Mass and burial) weren’t for 3 weeks for a variety of reasons.
This gave me the opportunity to plan a lot of family input into the service, 3 sons in law were pall bearers, 3daughters each did a reading, a family friend did the eulogy and I waited for inspiration for the music, choosing hymns and incidental music which meant a lot to us.
I think that helped.
I hope your family and friends will be be supportive and share your burden, but if I may say two more things
1This is YOUR family’s farewell, so do whatever feels right to you, don’t be steamrollered into any aspect of the service that you have not chosen
And 2 You will cope. Something will click in and even if the tears run non stop that is your prerogative as his life partner.
There will be better days and believe it or not, there will be worse.
I just kept the thought firmly in my head that Paw was NOT in that box, but in our hearts, in our children and in our grandchildren. I walk up to his grave in our village churchyard most days and I talk to him and I cry. Sometimes I sob my heart out, everything is “allowed”
I wish you strength and comfort in the days, weeks and months (even years) to come
