Your feelings are yours and yours alone. They are valid.
That’s great if someone is around and understands, but if this someone is nowhere to be found, that doesn’t make you or your feelings any less credible.
You feel how you feel, now, and most likely, soon, you will feel differently.
All of this is real; all of this is valid; all of this is credible - no matter how long, no matter how brief.
Breathe in. That’s your air.
