I’m sorry to hear you’re struggling.
Why don’t you pick one or two goals and start working on bite size steps towards them?
If you want to work in Antarctica, maybe research companies or places that you could apply to. Next, find out what they want of you. Then start adding to your resume/CV. If you need experience in something, that can be an another goal. Go do something that would help you work there.
Bite size steps is the only way that I manage to get things done otherwise I feel overwhelmed and do nothing. I’m like paralysed with this fear.
You can do this!!!
all the best
