Why Can't I Just Communicate?

Had to work for a school event today and it drained my social battery. Roughly a few days prior my friends and I made a plan to go out Friday of this week. I warned one of them yesterday that if the event were to drain me I wouldn't want to go out the next day.

The day ends and I let that same friend know that I'm tired from everything and that I would sleep in the next day, meaning I won't make it to the hangout. The thing with them is they won't express their feeling to the person and would rather complain online, kind of like me I guess? But it's easy to tick them off and they just hate you for the next day or so online.

I share a story that happened with an interaction with a parent ending with my picture being taken with their child (I'm still not sure why they did it). Later I found that the friend I told posted online about how they hate their conventionally attractive friends getting harrassed, they feel bad, but thinks they only friend them because they make them look better. Based on the context and how close the proximity of me telling the story and their post that it was about me. I didn't want it to come off like that, and I personally don't feel that way either. I didn't want to tell that story to make them feel inscure. I just couldn't express it to them because I cant let myself get that vulnerable, and also I didn't want them to think I was stocking their posts and accusing them. A follow up post went along the lines of how the unnamed person in their previous post ruined all the plans we had. I had told them yesterday that they could go without me and later on in a groupchat it was found that a friend's mom wouldn't let her go anyway.

It was dark so I offered for the both of us to be driven home by my dad, which they said nothing about until we both walk out the building towards the car. They then refuse to let me drive them home and chose to walk. I asked multiple times if they were sure and that I want them to be safe, after more talk I eventually gave up and let them walk. I have a feeling that they're currently just complaining to the rest of the friend group behind my back. I don't want to lose them, but living without answers is actually ruining me. I suck at communication too, so everything is just even worse.

I understand where they're coming from, but I really can't deal with this
