Late last year, I had accepted a research fellowship/startup position tied to a PhD position. The advisers were extremely supportive and I got my visa and was ready to move abroad. However, after working just a couple of weeks of joining, disaster struck and I had to leave abruptly due to a personal family emergency. My advisors were naturally upset but understanding of the situation. After a while, my personal situation got better and so I tried to reapply but by that time, the PhD position had already been filled. The advisers were kind enough to offer to possibly create a PhD position but wanted me to work at the startup in the meantime.
I had anticipated that the position would be unavailable and applied to other schools just in case; also, I was nervous about moving across the world to join a very small startup with a vague possibility of a PhD so I had to decline, especially since I wanted to prioritize securing a sure PhD position. Regrettably, I made the unfortunate mistake of telling my potential supervisors about exploring alternative options (I tend to be too transparent to a fault) and they became extremely upset. They sent a short but angry email telling me to stop absolutely wasting ("abusing") their time.
Honestly, the whole situation has caused me severe anxiety and depression, and I feel terrible. I'm seeing a mental health professional, but I'm plagued by a constant sinking feeling and dread. I'm sure I irrevocably burnt bridges here, but I was wondering if there's anyway to recover from the situation? Has anyone else gone through a similar experience of burning bridges in the academia? How badly will this affect my future career or has my academic career been destroyed completely?
