Hugs to you.

Can you take very, very, very small steps, one by one?
Everything in front of you is very huge right now, no wonder you feel so lost, I would feel so anyway.
I've been there too. Something that can calm me down is try to think something like: I can handle this moment, here, now. I can make this very little step. I know there are huge things in front of me, but how close they are, they are NOT "here, now". And I can handle "here, now".

You can handle "here, now". Please stick to that.
