Im in the same boat, try to distract yourself, stop yourself from thinking about them, not worth the mental energy. Its so hard but accepting it is the hardest part. I know how you feel, been having the same issue for a while and its difficult because you never dated them, but you become so mentally invested in a relationship that never happened that it can still really hurt. Just try your hardest to let them go
I feel the same way. It's really hard :'( I can't stop thinking of him.
