Help Throwing A Wedding For My Daughter

I am an unemployed mother of 5 and my first just got engaged. I am financially unable to give her a wedding like my mom and dad gave me and I feel really horrible and sad. I have worked since I was 14 and now at 49 I have been unable to find a job for the past 2 years. I am at my lowest in life I have ever been. At this time and event I should be full of joy not sadness and guilt. Does anyone have any resources? Thank you for your efforts, advice and leads.
