OK OP - I also suffer from depression (and work alone from home - think they're related, don't you?) Here's my self-care list each day:
DAILY
Get up
brush hair
clean teeth
clean and moisturise face and neck
Put on basic makeup (mascara, a smudge of eye shadow and lipstick. This is because I am very pale and if I don't, every time I glance in the mirror I see a grey, fat shadow of an old woman staring back, whereas if I put even a small amount of make up on I see a younger women with a more expressive face. If you look exhausted without make up, add some to your daily routine.
Get dressed in nice clothes. It's easy to stay in PJs or 'active wear'
if you work from home. But putting on a proper outfit that has a bit of personality also helps, when you catch sight of yourself in a reflection, stop you from feeling like a shadow.
I always put on perfume too, even when I'm alone, I just love the smell of it.
Healthy breakfast - berries and yoghurt with muesli or poached egg of wholemeal or porridge
Have at least one of your five a day - berries or banana, tomatoes and mushrooms or baked beans.
Take supplements if you need them. Vit D spray if you work inside all day and don't commute. Iron supplements if you are tired, L-Tyrosine etc if you have low mood. Work out what helps you.
Clean the kitchen and put a wash load on.
Fill a jug with water and make sure you've drunk it by the end of the day. Keep it by the kettle or near (not on!) your work desk Add sliced fruit or fresh herbs to it if you like.
Whenever you are boiling the kettle or heating up food at lunchtime, do some jumping jacks or high kicks or squats to get your blood moving.
Try to go for a walk every day - 40 mins to 1 hour is best but a brisk 10-15 mins round the block or to the shops is better than nothing.
Talk to someone every day. Even a quick catch up with a neighbour. WFH is so isolating.
Healthy lunch - keep easy salads, healthy soups and seed breads in the house. Have two of your five a day - salad or soup and a piece of fruit.
Evening meal - eat it with family if possible.
Make sure you have 2-3 of five a day and they are varied through the week.
Bedtime routine:
Hang out the wash load if you haven't already or put it in the drier or fold it if it is dry now. If you do this every day there's always a steady stream of clean clothes, bedclothes and towels for every one.
Bath or shower.
Wash hair every 2 days (dependent on hair type) and condition it
Clean and floss teeth.
Clean PJs every two days.
Write down all you achieved - however small
write down what you are thankful for. Keeps depression at bay.
I'm off to follow my own advice now! I don't always - but when I do, it works.
