Have or not to have a babyshower?

Here is the story:

I have two daughters. I never had a baby shower with my first due to me being young and the whole pregnancy was very unhappy for me. I had my second daughter 4 years later. I had a baby shower with her. She was born in 2017. Now, I am pregnant with our third baby, and it’s a boy. I have all the baby stuff I would need except for a few items like the extender for my stroller. I would never ever ask my guest or anyone to purchase it for me. The only thing that we are kind of in need for is boy clothes. I was thinking I will have a small baby shower and kindly ask people to bring boy clothes in all different sizes.

But here is another problem. My husband’s aunt is literally dying from stage 4 lung and bone cancer. The doctors gave her max a year to live but she ended up in the hospital last night with breathing issues. Now they say she only had a couple of days left. My mil is devastated as it is her sister we are talking about. I am not sure if it is okay or appropriate for me to be planning my baby shower while someone in our family is loosing her life. I feel like I shouldn’t be planning an event like this considering my circumstances. I guess I am just feeling guilty for being being as happy as I am while someone in my family is devastated and suffering. I don’t know what to do.

Btw I am due in November, so I have some time but would like to get everything and set up everything by october.
