Insomnia What Ifs'.

I wonder why every night at around 3 I always wake up and no I don't believe in that whole ghost thing when if you wake up at 3 it means like theres a ghost watching you or something like that. It's like my body made a habit for going to the bathroom at 3 every night for about 2 weeks now. Also maybe its cause I've been taking diuretics. Every time I wake up I think about my problems and I end up staying up for about 2-3 hours constantly and desperately thinking of a way to get out of these problems. I can't shake it off. Everyone is telling me that time will heal, but what if it doesn't? I'm scared because I don't want to lose something thats too important to me. But what if this is Gods will? What if its destined to be like this. What if I was destined to feel this much pain so for the future I think harder on how to make better decisions. What if life is giving me a lesson? What if I shouldn't even be worrying right now because its all a lie? But what if its not a lie? What will happen to our offspring? What will I do or say when she asks me the questions that I wouldn't know the answers to? What will people say about me? What if he really loves her? I have so much questions to ask and I've been waiting for answers. You should know me well enough that I wouldn't do something like that. It feels like I'm going to have a heart attack.
