[cassian is well aware he's certainly not the only person to suffer this, not the first or ever the last. but he always tried hard not to think about the others, mostly because he didn't want to care about them. being alone was safer.]

[it's different now, because there are people he somehow cares about, even if he's still figuring out the best ways to go about that. he cares about jim and his well being. neither of them are alone anymore, and that's a very odd if not comforting feeling.]

[he can't imagine what it would be like, if jyn were suddenly not here. it's enough to get him really feeling for how bones disappearing would hit jim.]

I am not sure it matters how new or experienced someone is in dealing with this. Some days and some times it's just... harder.

I would be a hypocrite if I told you to talk so someone, but there are probably a lot of different ways to remember you aren't alone. You will get through this, Jim.
