True. We do need to find ways to be happy on our own. Perhaps this is something you can work on? Finding things in life that make you happy or content? When I was at my unhappiest, I made a list of all the things in life that gave me happiness. Then I started to focus more on those things and on bringing those things more into my life on a daily and weekly basis.

That being said, it is perfectly OK to also rely on other people for support and socialization.
