Feel weird

Had a girls night.

Nice friends looked after them. With food and lovely bedding etc.
they stayed two nights
One friend I felt was using me. I feel like she always uses me for lifts etc.
I didn’t say anything but out of all my friends I help her and support her the most when she needs anything like lifts etc.
it’s weird but when everyone went home I felt like she didn’t want to go and I was starting to feel sick the day before. So even though I was sad to see everyone go home I knew I needed some time to rest and get better.

I feel like she is angry at me for being ill?
All my friends said they had a great time except this friend
And she has not responded to my texts asking is she ok. She hasn’t even answered my call.
I can tell she’s upset but I haven’t done anything other than look after them for two days. Make them food and I got the little sleepover goody bags.

I’m upset because I shouldn’t care but I do
