What you are describing doesn't necessarily sound like an issue with the tech sector, but rather that you are a bit burnt out.
My suggestion: try to take some time off, either by not working or just working on some very unambitious projects that give you time to relax. Do this for at least 2-3 months. Sleep, eat, treat yourself well.
Then slowly start tinkering with whatever tickles your interest (only once you feel like it). This can be a a tech side project, playing the guitar or bartending.
This recipe has helped me re-discover my energy in the past.
It might lead you to something in tech or outside tech.
Just my 2 cents.
