Dear @Monika,

I can merely repeat myself. I stand by the same recommendations, and I feel you haven't taken them seriously. I give you examples below.

"There is another lab who knows my PI, and they offered me (...)" -- I recommend you stay away from the influence circle of any abusive colleagues who want to take advantage of you. If you haven't negotiated any opportunities outside of his sphere, probably you haven't done any actual networking like I recommended. If you don't move, you stay in the same place.

" if I did well may be I could continue" -- this sounds like the oldest bait trick in the scam job market. My bet is that they want to take all you can from you, and give nothing in exchange. Like apparently has been happening where you are.

"I will feel a big failure" and other self-pitiful remarks -- you cannot control other people's actions, but you have full control over you own actions and how you feel. Evaluate your options coldly, come up with a logical plan, and execute it with bold steps. Any plan followed by bold actions will take you to a better standing. You are probably limiting the world (there are surely more than 2-3 countries you can actually go to) and your options in your mind.
