I'm sure on the outside I put on a convincing display that things are going okay. In reality I just can't wait for life to be over.
Are you having a rough go with things right now?
I think about jumping off the window all the time.
While it's okay to feel down sometimes, it's really unfortunate that you're having those thoughts. Have you considered reaching out to a friend or seeing a therapist? Perhaps they could help you get through it.
I should consider checking myself into a mental hospital.
If that is what you want to do, I say that you should. It is important to reach out to someone who can help you if you are having those thoughts. You are good for being that self aware.
