IT SHOULDN'T FEEL LIKE THIS

Yes, life works in mysterious ways! Who knows why and how things happen. I'm feeling so much for someone and I am just so confused about how things will work. I feel this insecurity that I just won't be able to live with out him. And I know I would have to now, a few years from now and maybe later.

Then, I've got all these fears and insecurities. It's eating me constantly from inside. It's horrible! So, here's my question: Isn't love supposed to be up-lifting, invigorating, something that gives security, warmth and makes one's life seem better? I'm sure it is; so why do I have this biting, sharp pain and insecurity? Why do i feel i won't be able to survive this?

Explain it to me someone.
