All kinds of creative things can help when you are feeling anxious or low. They can also increase your confidence and make you feel happier.
Activities or hobbies such as writing, singing, painting, cooking, playing an instrument, photography, knitting and gardening can absorb your attention so much that you forget all other negative thoughts. Experiment until you find something that suits you.
People who tap into their creativeness can accomplish amazing things and sometimes develop talents they never knew they had. Whatever activity you choose, being creative will bring you enjoyment and fulfilment.
