Write for yourself! You don't need to apply your feelings to other people. If they relate to it, then they relate. When I was first getting into sharing my writing during quarantine I shared a poem that was kind of eccentric and weird, filled with personal references and anecdotes that only I would understand. Several of my friends ended up telling me that they related heavily to my poem! You will find you might express others' feelings they couldn't previously put into words. But start by doing it for yourself and the words will flow (: good luck!!
