Interesting. I quit psychology/counseling and work in tech now and the thought of my work being absolutely meaningless gives me a lot of anxiety, I hope I'll come to terms with it one day. Correction, I'm sure I'll come to terms with it but the transition is far from being smooth and takes longer than I expected.
If it's meaningless, maybe try a different industry? I develop healthcare software and consider that quite meaningful. Before that I've worked on OA repositories, another thing I find useful. I'm not sure if I'd feel the same if I was work for a bank or something though.
I'm sure it'll work out when I gain more experience. :)
I was a child psychologist (specializing in development and planned to go deeper into social work) and it was/is the biggest passion of my life, so switching to tech feels weird to put it mildly.
IT is fantastic, don't get me wrong, I would not go back.
