R67 I hope you don’t mind, but I feel moved to say this. You & I share some things in common – sapphism, homophobic dysfunctional family, unsatisfying career, difficulty maintaining social bonds, etc. I have been battling my own self for what feels like my entire short life, culminating in years of depression, emotional instability, and total hermitage…until recently when someone in my life gave me something to think about: “take what’s yours, leave what’s not.” Disregard if it’s presumption, but it sounds to me like you’re doing what I once did, before I heard that; punishing yourself and isolating yourself for not living up to expectations that aren’t for you, anyway.
See, people like us? We’re mutants. Anomalies. Chaos agents. In an ordered, productive, heterocentric society, folks like us are not meant to exist. So our trajectories are not mapped, and we live in uncharted territory on the societal map of the world (arrr, Here Be Dragons). And that makes us special, makes us marked for some different purpose than whatever the Mad Men want to sell. We are here to wake people up, and show the planet that they don’t have to conform. Think of the breeders you know. Are they happy, really? Can they truly bear the pressures they live with forever? Would they choose their fate if they got to pick again? Aunt Ida was right, and don’t ever forget that. I’m confident freaks like us are meant for something else, having a purpose or responsibility beyond the understanding of the straight topside world.
Consider it. You rent - but you don't have a mortgage or the stress of upkeep. You're single - but you don't have fuckup kids or an abusive ex-spouse or a demanding girlfriend who bleeds you dry of time and money. You're alone and estranged - you don't have to worry about elder care. You're obese - you're liberated from the constraints of female beauty culture (horribly sexist and ageist as it is) and from the fanaticism of health-gurus. You also paid off your own debt, put yourself through College, and survived being kicked out all by yourself - that makes you a success and a resilient bitch. Give yourself a break, and some damn credit.
You say you don’t give a fuck about your health, and you don’t give a fuck about yourself or anyone else. Cool, that makes you free to do things the majority of people can’t or won’t do. Why not go out in a blaze of glory (I’d say blaze of cocks, but you know, lesbians) and do something to leave a bootprint on the saloon door before you walk out?
You also say you don't want pity. Good, cuz I don't feel that sorry for you. There are numerous fat lonely misanthropes who still became famous or successful and turned their lives into something, so that's not really a barrier or anything. I believe in you as you are. Like R73 says - you have a unique opportunity here to step off the vector, shift paradigm, a move not everyone gets the chance or the guts or the window to do (you have to hit rock bottom to win that prize).
