Revisiting my failures

I like to revisit my failures when I feel I no longer understand why I feel this way, but you can't really do that in real life; in real life it just kinda goes on, but online you can revisit your failures all you want. It's really silly why I get down sometimes, but it truly makes me feel like I can't go on with my day anymore. Wrong place, wrong time. Do you ever feel like your mind is so connected to something that it's almost like you are afraid of letting go, but you kinda give it away because it starts to become stressful and you feel or have a premonition that something's about to change or end? It's like the cord that attaches your mind with reality suddenly gets cut and you have an awful sensation that you are about to lose it, and it's like you gotta get a hold of yourself but that extra need to reattach yourself to your surroundings is the reason why you lose it... and it creates a heart ache. That's how I'm feeling now, somehow started the day really positive and for some reason my heart aches, but I think I know why. I enter a state of gloom every time, with no exception, that I could be doing so good, and suddenly, something or someone, would strip me off my confidence. No amount of convincing would change the fact of a heart ache or heart break... that's why there's time, that's why there's healing. Do you also know that stinging sensation that your heart feels heavy and then anything brings you down?
