My friends flake on me all the time...

I am a woman in my early 30s and I've recently relocated to a new city. I had a few friends who lived here already and was looking forward to connecting with them more. Since I've been in the city, I've hung out with them a handful of times but I find they cancel on me at least 50% of the time or more. I am actively trying to make new friends and met one girl who works in the same field as me. I invited everyone to go on a hike a few weeks ago and all 3 ladies agreed several days in advance. I booked a rental car, purchased some snacks to take with us and was ready to go the next morning. I have been exhausted from my work lately and had worked overtime that week but I was determined to make time for my friendships because I'm trying to put down roots in my new town.

One of the girls texted me at midnight the night before (when I was sleeping) to cancel. The other two texted me in the morning to cancel. All three blamed fatigue/not feeling up to it and two of them also cited period pains. Because I was the organiser and none of them know each other very well, they all texted separately and didn't know the others had cancelled too. I am certain they would have felt very badly had they realised no one ended up coming.

The following week I had plans with one of the girls and she cancelled again (in all fairness she said she was getting sick, and I know she can't help that). The next Sunday I invited another one of the girls over to mine for homemade Sunday brunch, she agreed the day before and then cancelled in the morning, again saying she's too fatigued and didn't sleep well.

Believe it or not I actually do believe these girls love me as friends and they have been there for me in very difficult times and shown up for me in other ways. I don't want to stop being friends with them, I believe we can show our friendship in other ways that still hold value. But I feel like I need to find other friends to do consistent outings/activities with and that takes time. In the meantime, it is pretty lonely and I don't really know what to do. Even my new friend can be pretty flake-y and it has me wondering if this is just the norm now? Am I going to make new friends just to find that everyone is comfortable cancelling last minute these days? I'm pretty let down by it at the moment.
