Best friend has no emotional capacity for me

My best friend of 12 years has been going thru some issues with anxiety the past 4 years. She sees a therapist and takes medication but in all honesty nothing has changed for her despite this. She texts me normally 70+ times a day with things she’s anxious about, issues with her family, things her therapist has said, etc. All about her. Been that way for years. We live in different states so that is the only way we communicate.

So recently I have been going through some issues with my health. I’ve been very worried about it and am hoping for the best as I get more tests done. I told this to her and she didn’t really respond. Just gave me a few words. Now she isn’t texting me at all. I texted her this morning and asked what was up. This was her response. Honestly this hurts so badly. Should I end this friendship?

“Well with all your issues with your health you have been making me really anxious and I have my own issues I have to focus on. I’m sorry if that sounds harsh but I don’t have the time or energy. I hope it all works out for you but until you’re able to help me through my issues again I will leave you alone.”

It feels like she just wants me as her emotional dumping ground and now that I’m not available to do that she wants nothing to do with me.
