For some background information, these past two years were rough, I (F28) had a lot of health issues. Not life threatening, but I'm learning how to manage life with chronic illnesses.

I've known my best friend (F25) for years. She was always there for me. We used to talk a lot everyday. Two months ago, after being diagnosed with another issue, she was trying to cheer me up and said something like "it's not that bad, it's not like cancer or being disabled". I told her it felt like a slap in the face, and I didn't expect that from her. She didn't answer. I knew she was having a stressful day, so I put it aside and asked her if everything was alright. She completely shut me down, and has been answering coldly since to my few attempts to talk. Over time, I stopped trying. But have the feeling I should have forced a discussion instead of letting the whole relationship rot. AITAH ?

I really miss her but I'm very hurt by her coldness since, and lack of concern overall. She even put on insta that she was in my city and didn't tell me about it. Over the years, I saw her make a lot of efforts for people that didn't deserve it, so it really makes me feel like I don't matter. I don't know what to do.
