I parked everything in cash after a bad year and now I can't get back in

Age 29. I sold most of my equity funds after a rough stretch last year because I told myself I'd buy back in once things 'felt clearer'. Shocking news: they have never felt clearer.

Current allocation on about 92k:
- 15% global equity ETF
- 5% bond fund
- 80% cash

Goal is long-term investing, horizon 25+ years, risk tolerance apparently lower than my mouth claims. Anybody dig themselves out of this without doing something dramatic?
