Our feelings are neither good nor bad, right nor wrong; they just are. Growing up as fatherless daughters, many of us suppressed our painful emotions rather than acknowledging them. As a result, we never learned to deal with them in healthy, constructive ways. By keeping our feelings underground, we may have struggled with drugs, alcohol, food addictions, problems in our relationships, and struggles with our careers as adults.
Therefore, you're doing everything right by acknowledging the sadness that you're experiencing now. It's perfectly normal and to be expected. What you're doing wrong, though, is watching too much of this coverage and spiraling into depression because of it. Acknowledging your emotions is a healthy first step. The next step is to respond to what you need at this time and practice self-care.
Talk to yourself in kind, nurturing ways: “I'm feeling down and need to do something nice for myself. I think that I'll take a walk, hang out with friends, dance to some music, or soak in a hot bath.” It would also be helpful to write about your feelings in a journal or talk about them with someone who can relate to your pain—perhaps, a friend who's also a fatherless daughter.
The images of Kobe and Gigi Bryant are beautiful, and it appears that they shared an enviable father-daughter bond. However, the photos we see of them (or anyone on social media) are just happy times. They don't reflect the complexity of human relationships with all their ups and downs.
I'm sure that you're not the only fatherless daughters who felt distressed while looking at those images. I'm glad that you recognize how they're negatively impacting you. Now, please step away and start taking care of yourself.
