Does gaining life skills like learning how to cook heal emotional trauma?

yes I think so because it helps you to be independent and this breaks any co-dependency left over from emotional trauma. Being able to care and look after yourself without whatever nonsense means you can rely on you.

Nutrition is very relevant to health and well-being, and helps to regulate emotions. Being confident that you can take care of you means that you are safe from many forms of manipulation. It can also help to raise your self-esteem.

Good Luck God Bless
