You decide if you are going to feel sad or happy. You must first realize that no one or nothing makes you feel any certain way. You decide all by yourself how you are going to feel. So decide right now how you want to spend the rest of your days. The first part of healing is surround yourself with positive people.
Nothing depresses people quicker than being around others who are depressed.
You need to let your family know what is best for you. Family wants to help and many times they get so caught up with trying to help that they start telling you what is best for you. What you need from your family is their support, NOT their advice. Tell them to please support your decisions or hold their tongue. You don't need people telling you what to do right now.
