Three weeks ago I was to meet a friend J in town, but she didn't show up. I tried phoning her several times on getting home and got no reply. So as she is diabetic and elderly I was concerned and I phoned another friend C who took me up to J's home in her car. The place was dark and quiet. C climbed through a window and J was almost dead in bed. She was taken to hospital by ambulance and was kept in 13 days and then came home. I visited her in hospital on 11 of the 13 days as, like me, she has no family and I didn't want her to be the only one without a regular visitor. C also visited her once. I have been to see her twice at her home this week and C came with me the second time. I also phoned on the other days to see how she was. Earlier this evening I phoned her and she said that C is our 'mainstay.' I am NOT saying here that C should have done more, because she did plenty and isn't close to J anyway. But it hurts that what I have done has not been appreciated. She doesn't value what I have done and this makes me feel like rubbish and makes me think why did I bother visiting her so much and why have I phoned on the days I didn't see her etc when none of it meant much to her? I remember years ago I helped her out when she was unwell and a neighbour also helped her. Afterwards she said that she was buying her neighbour a present for helping her. I didn't want a present but she clearly wasn't grateful for my help. It makes me feel used. Am I overreacting?
