You're definitely not alone!!
I've lived on my own a few times, but it always ended in an emotional breakdown. At first, it's fun and exhilarating and I keep up with work, bills, grocery shopping... but after not very long, those responsibilities consume my every thought. I become anxious and can't sleep, I dread each new task and will stay awake nights thinking about walking my rent check to the apartment office in one week, or putting a bill in the mail. I'll start to fall asleep and suddenly panic, feeling like I forgot something. I end up becoming miserable and nervous and have no free time, because all my free time gets filled with my worry that I will miss something and I make lists and lists to make sure I don't forget...
It sounds like OCD, but it isn't... I just get so afraid that I will end up forgetting something, because I know that the longer I do something that doesn't come easily to me (i. e. remembering to pay rent), the harder it is for me to keep up the energy to do it. I've been through this four times, now, and I always start with such hopes...
I'm living with my parents, like a lot of people on here, right now. I plan on looking for a job again soon, but not too soon... the last time was very depressing for me to have to move home, because I loved my job!! Because I've had so much combined experience living on my own, I feel kind of guilty so I try to be helpful around the house where I can. I do a lot of cleaning. A LOT.
Oh, man, when it comes to arguing with people on the phone I think I'm exactly like you, lol. Anytime I can't solve a problem right away, my mother ends up fixing it. Sometimes I'll ask her about the problem and she'll try to explain to me what I should say when I call back, but I always get so confused and overwhelmed that she just does it. In the moment it's happening, I can't comprehend why when you call to get something done it can't just be done! I don't care if I have to be on the phone awhile and answer questions, but do your job! The systems of businesses elude my comprehension. D':
