Depressed bf...

My boyfriend had had depression for awhile and recently there has been some problems going on in his fam and it’s making I worse,everything is getting worse for me too tho I am already sad pretty often and I feel like it’s making everything worse what’s going on with him right now.Its like all his sadness is effecting me...I’m not sure how to deal with this or when he’s sad what to do,it’s just really hard for me to be with him during this time he need someone...
