I can’t stop thinking

I can’t stop thinking about you. Do you even want to be with me because if you do tell me, I’m tried of thinking, “What if” I love you and I’m positive of this. I realized that she’s the source of my happiest and misery. When I don’t talk to her I feel super depressed I don’t know why this happens all the time. She doesn’t exactly know how I feel about her, I just have a hard time maintaining my sanity when we don’t talk.
