I guess you stuck on to your dreams a bit too long. Well, we all do, that's the point. Nobody can tell you that's a wrong thing, even if it sometimes seems logical in the real world.
Well, if I step into your shoes it might take me a while to listen to the suggestions of all these people who are genuinely trying to help you. Your brain just shuts off and cant think straight. You need to find a way to somehow let it out. Cant say go backpack for a few days because you have a family to take care of...but try talking to friendly strangers, do something you haven't tried before(in a good sense) that doesn't cost money, just somehow get everything out of your system, try unplugging even if its for 2-3 days and then come back and read the comments again. I'm sure you'll see things much more clear. The help is already here!
That was as honest and close I can get to feel what you might be going through. Having said that, its always easier said than done. God bless you! Dont forget to comment to this thread once you are back up and strong! :)
