I have CFS. I had the worst relapse ever last year and spent most of it off work.
I think it makes me more accepting of others. To people who dont know me I look and sound healthy, it showed me that almost everyone will have something they struggle with that you don't know about.
I have discovered that spending time in nature is really calming and healing for me (I'm not at all 'woo' but I often recover best after a blip if I have a change of scene and spend lots of time outside).
I have actually found this whole pandemic fairly easy to deal with (accepting that I have been more fortunate than a lot of people in that I haven't lost anyone and can wfh) as I've actually got good at trying not to panic and think the worst, count my blessings and take each day at a time. I'm not naturally like that so that's quite a big thing for me.
It's made me better at asking for and accepting help.
Also the pacing work has made me think about what zaps my energy but also what I enjoy and don't enjoy, I feel like I've discovered a lot about my own personality that I never knew before.
Its helped me become more organised because I can't do things all at once any more so I'll do tasks like cooking in stages sometimes, weigh out one night, prep another night , finish off another.
It's also made me stop running about like a mad thing trying to do stuff that doesnt matter. Like a lot of people with CFS I was a bit of a perfectionist, I'd have a party and have a million choices of food and drinks and not let anyone help. Now I'm like 'come round for beer and burgers' and spend more time actually talking to people. Although the need to do everything myself all the time keeps popping up but at least I recognise it's not good for me now.
Of course I'd rather be healthy and it's hard not to worry what would happen long time eg financially if I couldn't work but for now I'm ok. There are some shitty dark times and I sometimes hate myself for feeling like im letting my children down but it's not all bad it just means you have to live a bit differently to before
