I would say, Get the fucking rid of what is socially correct and be your own best friend ! If you should have only one great relation it should be with yourself, and guilt is the worst in a relation...don't feel guilty to have too much "friends" you have not texted, don't feel guilty to not have enough, guilt is guilt and as long as it is a feeling you tolerate in your life it will manifest in every possible form ;-)
And the social model is there only to maintain an illusional order, when at the same time it apparently generates more mental disorders in fact...why ? because people feel deep inside there is something else, there is something to search inside themselves and not outside in the "society", in the others....searching for approbation is what makes people maintaining a structure that is outside them...
Wheras the solution comes from the inside...befriend yourself...yes, have those friendship bracelet kit if you want and make all the bracelet for you, but not to show the society you have friends, but only for you, because YOU deserve to take care of your inner being...and everyone should do the same and little by little love themself and seriously, do we think people would go on searching outside the confirmation of their whorthiness ? would they take a gun and shout someone because they think they would feel better after ? No, everybody would care its own business in a loving way, which will benefit everybody..
Well that's my feeling ;-)
