i've been there. I also tried to think of new ideas to work on but I couldn't put any energy into it. I used to think I was a very creative person but even that I started to have serious doubt about. That's when I decided to take a break. I think you ran out of energy NOT because you're working in tech, but because you're working for yourself (This is pretty natural). Take a break and mindlessly work for someone else. After 6 months to a year you'll have recovered completely and probably be overflowing with ideas and energy.
