Snugs Is Gone- And I Am Struggling To Cope, What now? Options

[Sad parent]

My darling boy is gone. His cremation was today. I decided to observe the cremation. I was nervous, but I am glad I did this. It was a last chance to touch his soft fur. I am still struggling to move on. Everything I look at reminds me of him and then I feel so sad and empty. I am crying less now than I did a week ago, which is when my boy died. I have been reaching out for support, which is not easy for me. I even attended a pet loss grief support group.
How do I ever get another cat, when I will always compare that cat to my perfect Snugs, I can't imagine how I can be a good parent to another cat. I also don't want to go though this again.
My boy Snugs was beautiful, intelligent, and had a great personality.
Since he used to sleep with me, I am still having trouble sleeping. I know I took good care of Him, but there are times when I am filled with guilt, wishing I gave him more attention. I took him to his vet for regular exams, but I didn't know how important it was to have his blood pressure checked as he grew older. His regular vet never brought it up until it was too late. With vision problems and kidney problems, he bravely continued on a couple of more years, I wish I could go back in time and check his blood pressure before he had problems.

I received a paw print in the mail today from his vet clinic. I didn't know they took his paw print. I am glad they did. But it was a surprise. I was overwhelmed when I saw what it was. I put it down and have not been able to look at it again. It hurts to see his paw print and not be able to touch his paw.
I have not been able to do much with his bedding. I took it off my bed. It hurt too much to have it on my bed. I would wake up reaching for him.
I took good care of him, but sometimes I am guilty that I didn't spend more time with him. When I was busy, I took him for granted, assuming he would always be around.

I am very grateful for all of the support I have received. Thank you for your responses.
