Lowkey got mad and was rude to my bestie and now she’s ignoring me I don't know what to do?

So my bestie and I have been friends for over 2 years. We’ve stopped talking multiples times of months due to nonsense and either of us fkin up and once my ex caused issues. I felt bad so I did a surprise bday for her and everything. I planned it with her ex and our good friend. I felt she didn’t even acknowledge that I did it and planned the thing and stuff and she thanked the rest and told people that it was them. I let it slide. multiple occasions she’d act flimsy with sharing stuff while I’d give everything. We still make up, have our late night convo for hours etc. she knows my entire family history, how I’m financially fucked and everything.
I’ve noticed how she would make fun of me with my other roomie when I was seeing this guy for a month. They’d always joke and offend us. When that guys roomie disrespected my bestie when I was at his place I felt offended and pissed and let her know etc. I noticed she is getting closer with my other roommate and friend. they started planning stuff without me. when things ended with that guy, I got overwhelmed with all the pressure, family drama, finances, my self esteem everything and cried for 6 hours. She was listening but texting someone a dating app and laughing while I’m in pain. even when they cancelled one of our plans and didn’t update me I got mad af. I told her I’d join them for dinner but she refused to move it an hour because of their schedule and I had work which made it harder to reach on time. She kept asking me to move my mandatory shift which I told her I can’t due to contractual reasons and she wouldn’t get it and then I got pissed. I let her use my stuff but she makes a mess and won’t clean. says she will contribute but when it comes to it she won’t. I’ve tried telling her but she won’t listen and cause I lost patience she’s avoiding me. I did a mistake which was lashing out but she also has done worse and I don't know what to do.
