Is it normal to feel pissed about no recognition?

Okay. So I have this friend and she had a boyfriend whom we all liked and got along with pretty good. He was a pretty decent guy cause he was wonderful to my friend. She even told me I was his favorite friend out of her little group of friends. Well one day he just started getting sick and we couldn't figure out why. Eventually, they thought it was Lymphoma because of all the lumps on his neck. Now at the time, my friend and her bf were having money issues and couldn't see a doctor without 300$ up front. I lend my friend the money. After a few more visits, we find out he has Acute Leukemia. He's immediately taken to a hospital an hour and a half away from our town. I've already told my friend from the beginning I would do anything there was to do to help. Over the next two and a half weeks, I run back and forth from the hospital, bringing people to and from, washin clothes, take time off work just to stay a night or two with my friend and her family, as well as her boyfriend's family and friends. On August 2 of this year, my friend's boyfriend died from his short battle with cancer, but he fought so hard. I got a reckless driving charge the morning of, because he had slipped into a coma and had said on such occasion, only to keep him alive til everyone was there to say bye. I was one of the ones to hold his hand while he slipped away. I was the only friend there to comfort my best friend. I'm the one who took her home the day everything happened. I talked with her for hours on end.
Now it's been over a month since his passing. I was asleep on my friends couch while we were having a girls night. At one point in the night, I was listening to my friend tell the whole story to a new college friend. I was pretending to be asleep so I didn't have to deal with the sadness.Throughout the entire story, my friend does not mention me in the slightest. she named every person there when he died, except me. It was like I had no part what so ever. I know shouldn't have been eavesdropping but I had woke up to them crying. Should I feel pissed about no recognition? I felt like I had done something worth mentioning, but I dont want to sound like a total bitch.
