I'm starting to think watching heym too often makes me write super emotional and elaborate texts to girls that I usually never send
Why don't you ever send them?
I never send them because I'm scared to tell them my real feelings
Being scared of how they'll judge your feelings is normal but you should build up the courage to send one of them. See how the girl responds to it. Worst case she doesn't like it and nothing changes, but if she does like it you might have found yourself a new girlfriend!
You're making me consider pushing myself out of my comfort zone and I need your help to stay positive.
It's great that you're starting to to find the courage to tell them how you feel. I'm sure you'll find someone great to be with.
