I agree with the above. Sometimes getting yourself to do the stuff that is hard to do but important is really good. Even just having a routine of self-care activities can help you get into the habit, like putting your knee exercises in the calendar.
I’m gunna blame it on my super big family and countryside childhood, but I have always been really bad at brushing my teeth and washing my face every day. It wasn’t something that was ever instilled in us as being important. Something that helped me was going out and buying products for a really over-the-top 10-step Korean beauty regime. We’re talking cleansers, toners, ampoules (?? I still don’t know what this is), moisturisers etc. I make a great ritual-like ceremony of it, starting and ending every day with this stupidly over the top process. xD Also being in the bathroom for that much time helped make me brush my teeth twice every day too. It’s silly because I made it harder and more time consuming to do the task, but having my own special ritual and products actually helped. Also, my skin is so soft rn like omg sometimes I just rub my hands on my cheeks for the fun of it hahaha
It can be easy to turn your self-care activities into stressful piles of pants though, so having a long bath really can be the right thing to do. For example, I got really burnt out towards the end of last year and decided this year that I would dedicate more time to reading and exercising - two things I enjoy and find relaxing. But what’s happened is I am putting pressure on myself to read every single day (I am actively reading one book on the kindle app, two physical books and one audiobook)((my friends and I have a book club and I am super stressed rn because I have until 5pm tomorrow to read 200 pages, and I’m going to a meetup tonight so I probably won’t finish reading until 3am)), and meet over-the-top exercise targets even on days when I am super busy. So I guess a piece of advice I should take, and would recommend to others, is to know when to step back from your hobbies and do something different. Your self care activities can be self destructive if you take them too far.
Also, making that phone call you’re avoiding right now won’t (probably) be half as stressful as spending the next two weeks low-key panicking about how you still need to make that phone call. Getting someone else to phone them while pretending to be you is also a valid option imo. xD
