I'm so sorry for your loss. Just keep telling yourself "this too will pass"
I recently just passed the one month since my Drew passed. He was 37 year old and died from blood clots to both lungs. Seriously, you just need to take it one day at a time...that's really all of us can do. You will have days where you feel like wonder woman and days you feel like a shell of a human being. Remember to breath, drink water, and have plenty of tissues on hand.
