Sadness does stem from dwelling on negative thoughts and emotions. Perhaps go out for a jog or a bike ride, or do yoga every now and then, because physical activity is not only good for your body, but it’s good for your mind. It’s okay to feel sad, but when you do maybe listen to your favourite song or watch a funny tv show (eg. parks and recreation). Taking long baths and wearing your favourite outfit also helps.
But it’s also important to share your feelings, it’s never good to keep them bottled up inside. Whenever you’re sad talk to a friend or parent. You might not want to explain why or have a long conversation about it, but saying ‘I’m sad’ is enough. Contact comfort is also extremely important, get a long hug from a parent or a friend and you’ll see that you already feel better.
And in the end, always try and remember the happy memories and thoughts. Keeping a journal, or a photo album, or a video diary can help channel your positive thoughts and help you keep a happier mindset.
