How to cope/ what to do

So my husband will be traveling for work. This job is for about a year and a half maybe more. He works Mon-Sat.

Wont be coming home till Sunday and will leave early Monday morning for work on the weeks he can come home

I want to learn how to cope because I recently got diagnosed with sever depression and this isn't helping at all. I want to be supportive because I know it's good money. But the fact I only get to see him once week (maybe)

I would go with him but our daughter is still young now that I dont want her to be stuck in a hotel room in a city where we dont know where anything is. I'd rather stay home with her... but I know we can video call, text. But hes constantly working and it is heavy work so he gets put extremely exhausted and just goes to sleep.
