What is the true purpose of friendship

Recently I've found myself friendless the reason well thats because I set boundaries and refused to settle for the scraps of companion ship My so called friends  thought would be okay to give me. Something that no one talks about is the hardship of creating and maintaining your friends in your early 20s. I guess thats something the older generation never struggled with but it is common in this generation. I don't know if it has to do with the fact that you lose most of your friends from high school and then have to start over again which can be daunting for most or for the fact that as you've gotten older the friends you've made when you were in your teens no longer suit your needs as you've grown. Either way losing friends or not having friends SUCKS!!!! but its not the end of the world I find that the more we rely on having friends the more we've become afraid to be by ourselves the more lonely we feel because as soon as the party is over or the hangout is done and your by yourself again that's when you yearn to be with friends again just to not be alone by your self. Is there a solution? Well the best solution for me was to learn how to be by myself I realized that there is no one who knows me better then me what makes me sad, happy, angry the things I will allow the things I won't these are all things that I am the most familiar with when it comes to myself so I had to put the embarrassment and shame I felt from not any companionship to the side and search within to find myself without anyone else helping me and to be honest it sucked so bad for the first two weeks and then I realized I love it I love not being anxious when someone makes a joke and im not sure if it was shady or just playful. I love not having to feel the gut wrenching despair I felt as all of my "friends" hung out with each other and no one invited me it felt like a big weight was lifted off of my chest and to be honest I don't see myself getting any more friends any time soon not until I'm fully healed from within. Im sure my people will come eventually but even If they don't ill be just fine. -Blue
