Needing some time away..

I've been so tired and extremely overwhelmed 😵 my daughter is almost 2 and a half, my son just turned 4 months and I am just so tired. I barely sleep, and when I do it's always interrupted. My body just physically feels so worn out, I haven't been eating properly or even drinking enough water. My husband is always working so I feel so alone all the time☹️. I just need a break, maybe a weekend away.. but it feels impossible and I know I'd feel guilty. Ughhhh I know this is a precious time in my life but I'm tired.
