Depression

So lately I have just been really depressed and I have no motivation I recently went on vacation for my birthday but all I could think about was my grandpa who passed away last April and my nephew who passed away in November I just miss them a lot I think about them everyday no matter what I’m doing. I have no motivation to clean my house or even to get out of bed most days, sometimes I go 4-5 days sometimes without even brushing my hair that’s how bad it can gets and the only reason I get out of bed is to go to work the 3 days I do work I’m just having a really rough time and I feel like I have no one to talk to
