They probably think you're a middle aged, miserable, menopausal what not anyway and won't be surprised
More seriously, your health and well being are a far higher priority, and your loved ones would or certainly should understand if you have to prioritise your budget.
You may have only been joking, but sometimes presents, giving money etc does get out of hand and it can be useful for one event to trigger a review and cull. Slightly veering off-topic, but it's also an anxiety and mental health issue. A few years ago, MrLily was made redundant, nearing Christmas finances were still tight. I had been doing gifts or money for my cousin's kids, the stepdaughters and their kids. So, I explained to everyone we weren't doing anything for anyone at Christmas, and it would probably then extend to Birthdays.
I haven't ever resumed. We never received anything from them anyway. My cousin's kids are now adults, Mr Lily's side don't even send us Birthday or Christmas cards and we never or rarely see any of them, so, I just thought, sod it and never returned to sending anything.
