Ooh fab question.

I would say that things vary for individuals - there's no one thing, but things that tend to help daily are (obvious but still helpful): trying to move your body, eating well and sleeping enough (if possible!), trying to treat yourself with kindness like you would a good friend, trying to spot things you enjoy and things you feel proud of throughout the day.

Things that are usually unhelpful: too much of any one thing - e.g. too much isolation or too much busyness, not enough rest (even if it's tiny micro rests in the day), beating yourself up about things, ruminating on things that have already happened or worrying too much about things that are out of your control.

It's obviously easier said than done to make changes to these things, but they are worth considering in my opinion! There are more ideas in my most recent book which is only 99p on kindle for a few days: https://www.amazon.co.uk/Year-Change-Your-Mind-Therapy-ebook/dp/B0B4BTF8RH/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=&sr=
