How to change for the better and be happier

Remember that you don't have to solve everything and fight by yourself. There will always be people who do genuinely care about you even if you don't feel it. Their ways of helping might not suit you, but it doesn't mean that they do not care. Just tell them what you think you need and if talking to them still doesn't seem to help, please consider seeing somebody more qualified to support you. Don't allow yourself to be comfortable with being sad. You deserve so much more than just pain and tears, you deserve more than just feeling numb and empty. Human emotion is meant to be felt.
