Disappointed about my hen do

I get married in August and my MOH has been planning my hen do since last summer. With 5 days to go it has gone from 12 to 7 and I just feel so deflated by it that I just really don't want to go anymore. The people who are not coming are not coming for very genuine reasons- my sister is having emergency eye surgery, my fture MIL and SIL are not coming are my future FIL had a siezure 3 days ago which means they can't leave him alone, two families friends can't come either because of other family situations. I completely feel for them and I understand why they are not coming but at the same time, I just feel servrely disappointed and I just feel like my hen do is not going to be special and meaningful anymlre with so many important people missing. I just don't want to go. My friend has spent hundreds and I know that she is very disheartened too. I am finding it very hard to be excited. I suffer from bad anxiety and I can't quite seem to 'get over' myself. I know I have to go, that's not a choice but can anyone give me some words of encouragement. If I am honest, I just feel very sad and deflated and if I was going to do this again, I would rather not have had a hen do. TIA xx
