I feel like I would be the best friend and best lover in the world and I deserve all of it. I'd just be a broke one. But apparently I'm just repellent because no matter what people are just never interested in me. I probably have the personality of a fish. But a very loyal and caring one. Also I can't speak properly, words just don't come to me so I get an automatic -100 debuff on charisma whenever I open my mouth.
I don't feel miserable about myself despite my failure of a life because I have big delusions of grandeur and I'm 99% sure I will be remembered long after I die if I put my mind to it (even though I probably won't).
I think the trick is to fake it till you make it to manifest everything you want. My cousin manifests and she got absolutely everything she ever wanted down to the last detail without moving her butt, so me and my family now all believe in the power of the imagination. My mom was telling me how it helped her too. Anyway the point wasn't about manifesting, it'll upset robots if I bring it up, I just be speakin' off the cuff.
Still, I don't think there is a name for what you have. It's just called thinking you know what your value is while having mood swings.
