Hello there,
I also lost my husband in June. He was the same age as your husband and died from head/neck cancer shortly after his diagnosis. He also had a birthday in August, would have been his 53rd. I guess he gets to be 52 forever now.
I don't have any wise words, it still feels very fresh. I still have days where I can barely get out of bed. I talk to him constantly and miss him dearly.
Thanksgiving was so unbelievably difficult. I gues I dread Christmas.
One thing I have asked friends and family for is to invite me to things they are planning and to keep inviting me, even if I can't always show up. Sometimes it's nice to hear other peoples conversations and be distracted, even if it is very temporary. Sometimes, it's too much effort to leave the house.
Don't be afraid to ask for help. Most people want to help, they just don't know what you need.
For me, I feel like people are getting back to their regular lives and our friends and families are moving on. Here I am stuck, missing him and feeling like a basket case.
Not much help but maybe some solace in knowing there are people that understand your pain, as much as they are able too.
Take care.
