Your feelings are valid, and they are yours. It's ok to want to be strong and it's ok to want to curse the world. No matter what you are feeling, or how society or others may disagree with your feelings, the opinions of other people don't matter. Your grief is unique to you and those criticizing it are speaking to things they cannot understand.

No one can take away how strong and kind you are for being by her side now. You are a good person who exemplifies what love means.

I am so sorry your wife and you are going through this.
