Lightquest...I'm so sorry that you have so much going on at once. Both losses are significant and grieving is definitely natural.
Feeling sad and bad are very valid feelings now, please don't beat yourself up. I'm grateful that you have a kind and loving heart and feel these emotions and that you aren't made of teflon and can let significant loss just roll off of you. It's hard to go through such emotional times, but going through the pain helps us get to the other side and a better place. Please remember we are walking with you. Sending lots of hugs...I hope tomorrow is a little less painful.
