Should i talk to my husband about this?

i've always been a rock when it comes to emotional stuff, and i know my husband values that about me alot, but lately i'm finding myself really struggling emotionally. i'm a stay at home mom with a 1 yr old and 5 yr old, and they do push my ons, but its not really them. i lost my sister and my mother a few years ago and they were pretty much my only support system aside from my husband. i think its getting so bad now because he's working 7 days a week 12 hours a day with an hour commute each way, so we really have no time together. we just bought a place that we are trying to renovate but there just isnt the time to do it so thats getting to me too. i'm just really starting to feel like a rubberband thats being stretched and stretched and i know at some point i'm gonna break. but i don't want to make things harder for him, he already feels horrible about missing so much time with us and not being able to get us in the house yet. should i just keep suffering in silence or do i need to tell him what's going on? and i'm not having a nervous breakdown or anything, i'm not wanting to hurt myself or my kids or anything- i just always feel horrible, no energy, sad, angry, etc.
