I would take the lost money as an expensive lesson in investing.
What did you do right?
What did you do wrong? (I'd suggest going all-in was probably one thing).
Look at your biggest bitcoin trades and analyse the good and bad ones.
See if you learnt anything from your experience. Who knows, bitcoin may go up again at some point in the future. If you learn from your bad experience, maybe you will make the money back.
Don't get too worried about it. You're getting a lesson in dealing with hardships and we all know failure is the key to success, right? You got an experience from this that many people who didn't know about bitcoin didnt get. Better to have ventured and lost than not to have ventured at all.
The stress of loosing a ton of a money is actually a good experience that hardens you to deal with other difficulties. Many people cant deal with loosing even a small amount of money. Who knows when this experience might come in useful in your life? In business, investments, etc. You dont know whats around the corner.
It sounds like you need a break. You can always sell your coins now if you dont want to worry about them going down, and then buy them back later.
Oh yeah dont listen too much to the peeps on these forums who have got their head in their asses
