You have to find happiness on what you have, I know having the feeling of sadness and emptiness isnt easy. It feels like nobody cares about you, seems like nobody is capable of understanding your so called miserable life and you will also start thinking of what is the purpose of your life until you become depressed and wish to just died immediately. Let me tell you that suicide isnt an option so you have to look for your happiness even when you feel alone be strong. If youre not that string enough you can fake it, sometimes faking that you're strong isnt bad because it also makes you strong even if it just for a show. Surround yourself with a lot of positive person they can boost your confidence, yes its peaceful to be alone sometimes but make sure you dont feel lonely because if so it will just make you sadder. Always look on tge bright side.
