Public Triggers are the worst... I remember I was in the grocery store with my mom and one of Drew's and I's songs started playing overhead. I ran behind a case of chips and cried uncontrollably praying to God no one would see the blubbering mess behind the chips. I just wanted the song to stop playing and then to die and disappear. My mom said that this was a sign he was giving to me. My grief is way too strong and fresh to see any signs of him at this point.
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.
