Hi Tonya,
I feel your grief and it seems like the pain is unbearable. My daughter just turned six too and my husband passed away on Thanksgiving last year of stage 4 tongue cancer. Parties and events will not seem normal for a while.
My husband's last party that he celebrated with us was my son's 3rd party in October. He was in a lot of pain and made an appearance for an hour, which I am so grateful he did.
Now he's in heaven celebrating with Jesus. For all the suffering he endured, I am so glad he is resting comfortably now.
I feel your pain and will forever speak out for early intervention of oral cancer.
