Your struggle doesn’t have to be worse than someone else’s in order for it to be valid.
A lot of times we stop ourselves from feeling what we're feeling because we don't think we should be "allowed" to feel that way. We feel guilty for our emotions because "it shouldn't be a big deal," or "somebody else has it worse." Gratitude and perspective certainly have a place in helping us see our issues in the bigger picture, but never invalidate your feelings because somebody else makes you feel like they are not worthy. Your own journey and own challenges are valid and should be respected. It is never a competition.
