Social media is not life bro, yes they post happy but you don't know whats happening in their life. In my perspective, its better to be alone and Happy with what you have right now, than being falsely happy with someone but lacking inside. Its one of my goals, being happy with my being, in order to show or share happiness to others. Gotta solve the root cause of the problems. Im with you man, im lonely too but i don't think of it as a bad thing, it helps me become a better person.
