Seriously can't stress it enough, just tell people how you feel about them. It's hard and it's scary and it's daunting to open up but Jesus what is the point in feeling for someone if you can't tell them? Who cares if you look like a **** fool telling someone how you feel, you'd be even more foolish to not say a thing. People leave, they die, or things fizzle out; it happens. It's pessimistic but that's realistic; it's life.
One of my favorite lyrics is from Ron Pope- "Beautiful things never last, that's why fireflies flash." It's so true. Moments and people come and go and if you feel for someone just tell them then. I don't want to have someone feel something for me and just let it sit in his or her mind, I want to know about it. So if you love someone say something. If you hate someone, say something. If you're thankful, if you're annoyed, if you're happy, if you're devastated, if you're unsure- say something.
It's such a cliché but life is very honestly too short to keep quiet when your heart is thumping so loudly in your **** chest because you're too nervous to open your mouth to tell someone what they mean to you. Tell people. Write to people. Do something about your feelings. We feel and letting your feelings slip under the radar, to me, is a shame. I know we all express ourselves differently but for crying out loud at least let people know what they mean to you, because someday you may not be able to and you may wish you had said something. You know what's scarier than opening up? Leaving things unsaid, leaving your feelings to your own heart and mind, letting people go unnoticed and unappreciated or uninformed. That's scarier than opening up your mouth to say something about your feelings.
