Regretting bridesmaid choice

Hi all


I’m worried I’ve made a silly rash decision in respect of a bridesmaid. I don’t have any friends really I’ve never fitted into groups and so when it came to the wedding I did have a total panic about bridesmaids. I have friends but they are all the girlfriends and wives of my husband to be but I don’t think they would wanted to be a bridesmaid for me.
I have my sister and one friend I’ve known since primary school. My other half is having 4 groomsmen. Recently I’ve had a very tough time health wise and a friend from university has been making a lot of effort, checking I’m ok asking if I’m ok or need anything and just being a good friend. I didn’t ask her to be my bridesmaid at first because although we lived together for years after uni we were not too close. I also always felt like I was the joke at uni my housemates would laugh at me when we went out dancing or just take the Micky out of me and use to really hurt my feelings, I am a very sensitive person and I don’t think it was ever intended to be nasty. But that was over 8 years ago and I do think people change and grow up. we maybe see each other twice a year and speak every month or so. However when thinking about bridesmaids I thought seeing as she has been a constant in my life it probably was not very nice to not have asked her, she also had asked me years ago to be her bridesmaid (she didn’t get married in the end). So I asked her and she was delighted to accept. But I panicked and just asked her without thinking it through.
Then I started googling and people were saying how important a bridesmaid is etc etc and I’m having a total meltdown I’ve made a massive mistake asking somebody im not even close too. The issue is I don’t have any friends and quite frankly if it wasn’t for my sister would have ended up with no bridesmaids. To me a bridesmaid is not this big thing they get ready with me and walk down the aisle and that’s it but online I see lots of people saying they regret their bridesmaid s etc. I’m conscious because of this I’m asking my photographer for just a few photos of bridesmaids but mainly ones of us with out family .
I’m now in a bit of a state does it matter I’ve asked somebody I’m not overly close to when I don’t have anybody else to ask or should I make up an excuse and try and just have my sister.
