Even more so lately, sigh

I am the youngest of 8 children, so one wouldn't think this would happen. Four siblings have passed, and of the three remaining, one has not spoken to me in over 20 years, another thinks I never do anything right, and the third, whom I moved out of my home state to spend more time with, gets mean and abusive when I startle because of my PTSD. I sometimes feel as if everyone who actually cared about me is gone, though I also acknowledge that is probably a self-pitying attitude. I turned 58 last month, and decided I am just done with people who activate my bullshitometer, even if they are family. I like being alone actually, though I do struggle with loneliness sometimes. Thank God I have my two lovely cats: they are sweet, funny, and affectionate, and all I have to do is give them kibble, lol! 🙃
