Ask HN: Lost my passion for development, anyone else been through this?

After 7 years of working as a professional software developer I have realized this is not my passion anymore, and have started to doubt if it was a passion for me to begin with. I feel I'm not smart enough to keep up, I feel I will never be anything close to a "hacker", I am stuck being an average programmer. I have tried building things but it all seems like work to me, no matter how interesting the project might be or the technologies I choose. I have tried taking courses via coursera, learning new languages and technologies, even going back to the fundamentals learning algorithms, compilers and so on but again I lose interest, it all seems like work, makes me feel too dumb or stupid, not fun, and work has become something I dread and its making me miserable, I can only wait for the weekend to come and get drunk.

I live by myself, recently moved to a new country where I don't know anyone, but I have a mortgage and development is the only thing I "know" how to do and the reason I moved countries. I am still trying to find my passion, music has always been something I love, I am teaching myself electronic music production and guitar but at 30 I don't see myself making a career out of music or anything else for that matter.

Has anyone else been through a similar situation? is it possible to reignite my passion for software development? is it possible to switch careers at this stage in life? if not then how can I make the best of this situation?

Thanks HN.
