If you go back to the first page in this thread and start reading up until the end, you'll see that a lot of people that are now saying "you will recover, just give it time" among other good advice, once found themselves in the exact same frame of mind you are in now. Ask yourself this: why would you be the exception? What makes you so different that you would have caused permanent damage? The answer is: nothing. You are like everyone else that has gone through this and like everyone else what you are experiencing is causing you to see things darker than they really are. Which is completely normal, do not get me wrong, I really understand as I've had my fair share of horrible comedowns as well, I'm just trying to put things into perspective a bit for you. You are not the exception, you are the majority, you too will recover, though it takes time

take care of yourself man, you will one day be able to look back on this as a learning experience. I wish you all the best. Listen to your fellow posters in here, they really know what they are talking about and they understand it better than anyone
