I relate to every single thing with quiet BPD except this fp and taking things too seriously, i have worked on my confidence, co-dependence and used stoicism to somehow manage some stuff for like a year at that time I didn't know this fucked up disorder is the tree and my traumas are the roots of it.  
I do have a friend but I don't obsess over them like in memes and I have been trying to be understanding for like a year too so those black and white thinking are not that bad compared to other people in this sub.
