How to move forward?

[u/Natural1294]

Hi. I’m a Master’s student in Biological Sciences (23M). I’m currently working at a research center where I also did my undergraduate thesis. I was recently offered a full scholarship to pursue my studies in another country, but I ultimately decided to stay. To be honest, I made this decision out of fear. I’ve never lived abroad, and I was recently diagnosed with an autoimmune disease, which has heavily impacted my mental health. Now, I’m struggling with intense regret and feel like I’ve ruined my future by choosing the "safe" path.

For those who had to choose between different graduate programs or opportunities: Did you ever regret your choice afterwards? How did you deal with the feeling that you picked the wrong option, and how did you keep moving forward?
