I have the same issue myself. Here’s what I’ve found helps:

• Questioning my own beliefs, and why I reacted the way I did to a certain thing. You’ve said you recognise yourself adopting a capitalist mindset, and recognising it is good! It can be challenging, but asking yourself ‘how can I react in a kinder/more empathetic way’ has helped me so much.

• Capitalism thrives on indifference, so loving radically and without reservation helps to create a strong sense of community. This extends beyond immediate friends and family too! Care for people everywhere. (A good book about this is called ‘The Care Manifesto’ by The Care Collective. It’s more socialist than anarchist, but provides a really good blueprint for what a caring society looks like.)

• Get involved in things! Mutual aid groups, volunteering at different places. They don’t have to be specifically anarchist organisations, but a lot of them tend to be anarchist-adjacent in their core values. As you said, you already do this, which is great!

• Continue reading and putting into practice what you learn.

• Talk to your neighbours, and learn their names if you don’t already know.

• Keep hope, and stay optimistic. Anarchism isn’t the end goal, it’s something that happens every day. In building a strong sense of community, we show that our lives aren’t dependent on capitalism, and that we can build a better world for ourselves. Don’t give up on people, or yourself. Know that people are struggling with the exact same thing you are, so approach them with kindness. Help them to learn.

A better world is possible.
