My experience with both my parents is that grief has a lot of down sad things but I was also really emotionally raw in the first year after each of them passed. Flowers smelled more intensely my relationships were hotter and I was more willing to risk. I was going for it a lot more. I was 'unsober' and I wasn't playing by my rules.
I'm lucky to have family around me. Otherwise I'll be taking the risk of falling in love with myself.
