Attempting to overcome my fear

So a few years ago, I celebrated my 15th birthday and invited all my school friends to my birthday party but not one single person from my school showed up. We rented hall and all. My parents spent so much money planning the party for this as this was my first ever party. I even saved up some of my pocket money towards the party. I was bullied my whole secondary school years and now I think of it, I was stupid to think any of them were going to show up. The only people at my party was me, my younger sister, and my parents. I cried so much that day and 15 years later, I still have trauma from that day. Now the thing is that I am now a mum and as my child is growing up, I am starting to worry sick because I don’t want my child to experience what I did. For example, my six year old daughter badly wanted to become one their school councils but unfortunately she didn’t get the role because none of her classmates voted for her. I remember how she started crying when she told me about this and I had to fight my tears because it just brought back so much memories of my own secondary school life. The other thing is that every year over the past three years, my daughter has asked for a birthday celebration with her classmates but my fear is for the same thing that happened to me to happen to her too, so we haven’t just been going on vacations instead to celebrate her birthday. Her 7th birthday in November and she is asking for a kids birthday party with her classmates invited. I feel like I want to give this to her but I am worried about the other children in her class not showing up and sadly none of my own friends have children that I can invite. I don’t know what to do
