回复：32岁，女，已婚，无孩，图像处理专业

The best strategy is to namely keep your current job before landing next one.

I would:
- counter-propose to your boss to cut your working hours down to no more than 20 hours per week. You need to firmly stand your ground on that. It's much easier to find next job while still have another one. It's to large extent about perception in job hunting.
- Fully use >20 hours each week to find jobs. 图像处理专业 should not be that hard to find another job.

Good luck.
