I Realize I Sound Horrible, But it Doesn't Change the Fact I'm Miserable

Dear Experts, I have a job. It pays the bills. I take care of sick parents so I need a job that earns a decent income. I'm good at this job. I'm in the tech industry. I've been doing it for 20 years and am an expert in my field. I can do the job with my eyes closed. I should be happy with that... but I'm not. I am an artist and as hard as I try to re-invent myself and find a way to put art into my career, it doesn't work. There is nothing I can transition into that will cover my expenses and let me do what I love. I realize how self-absorbed I sound in this economy - trust me, I tell myself I'm being a horrible person daily. But, no matter what, I can't shake how sad I am and how much I want to find an new career in the arts. What do I do? Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
