Reassurance/clarity needed

Looking for some clarity on how my mother in law has been acting and if I’m overreacting by being so stressed by it


So we started planning our wedding nine months ago and we are two weeks to the big day
For the last six months my mother in law has had some sort of involvement that she has created a drama about - First was inviting her extended family we don’t ever see - I wasn’t happy about this at all and made it clear but she guilt tripped us with my fiancée’s grandad so we invited them (they RSVP’d saying no)Second was her outfit and constantly sending me dresses with pink even though I said to avoid it as it was the bridesmaids colour - this went on for a good six weeks before I lost the plot and told her where to go shopping Third was hair - i asked if she would like to use the hair stylist I’ve arranged and she declined because they won’t know her hair then three weeks ago asked if she could brig in her own hairdresser to our getting ready room (where the hair stylist and make up artist will be working together around the bridal party) so I said not there but fine for her own hotel room Fourth is make up artist - she has insisted on having a make up trial before agreeing to use the MUA but leaving the decision to do this until last week and deciding she won’t do a trial or use the make up artist which means the schedule has changed three times
Honestly she is the only person who has caused me any stress other than myself and has also been on mounjaro and had a new set of veneers all for the wedding and I’m left completely exhausted by the hassle of her and the main character energy
Am I right to feel this way??!!
