Burned out, how do I get out of the rut?

Hey HN, I'm a fullstack (mainly frontend) dev based in Germany with 3.5 YOE. I recently got fired while on sick leave (burnout) and I'm now slowly recovering (therapy, sports, rebuilding sleep, the usual). Also got diagnosed with autism + ADHD late in life, which explains... a lot in retrospect. I'm not looking to jump back in tomorrow, but I'm trying to gauge the market realistically. A few specific questions for those who've been through something similar or are currently hiring:

1. How honest should I be about the burnout / being fired in interviews?

2. Has a late neurodivergent diagnosis helped or hurt anyone's career perspective?

3. Is the German market still open for mid-level devs, or are we in a serious freeze?

Any honest perspectives welcome - good or bad.
