Many of you are in love, and that love is sincerely reciprocated.
I'm happy for you and your significant other.
But true love doesn't visit everyone.
In the absence of love from another, it's that much more important to LOVE YOURSELF.
Cut yourself some slack. Recognize the parts of you that are unique, and bring security, happiness, and contentment to those around you, be they pet or person.
Just because you're alone doesn't make you less worthy or less lovable. You are LOVE.
