Working at home issues

I am so frustrated I have a customer who sent me a pretty bad stuff to work with so she said she wouldn't be picky. So  I thought, ok this will be pretty easy job and now that I've done she's picky. I worked on it the best I can from what I can see so I just emailed it to learn this is the best I can do based on what I have, sorry I can't do more. I'm pretty much just ending it because it's so frustrating. Physically or mentally I just can't do this work anymore. I get so discouraged. Either I hurt or I can't focus, and if I take my medicine I can't work right on things as my hands won't be steady.

Who would hire ME?

After being told if I want more money, I'd need to work for it (taking care of 4 kids isn't enough work apparently), I've begun thinking about getting a job. What kind of job could I tolerate? I can barely muster energy to go grocery shopping. WebMD has a page with "workplace modifications" an employer can do to assist an employee with Fibromyalgia. It is unrealistic. If I was an employer,I wouldn't hire somebody I had to make modifications for. I've been working from home for the past 12 years. I suppose that makes SSI Disability income out of the question. Anyway, I am depressed. I pretty much just slept all day.
