Wow this seems to becoming a popular trend!!
Hard answer: no, it is not going to just "go away" one day. You're not going to simply forget it happened. That should make you feel pretty damn shitty right now.
And here is why.
What you're in right now is a depressed state. (yah - you coulda told me that). This trip you had was so monumental to your brain structure you're not going to be able to simply forget about it. So get that notion out the door.
The easy answer is in time, you'll figure your path out. (millionth time I've said this, but) I've been there. After a year I still struggled. After two fucking years I still had nights where I'd have a panic attack. I don't want to scare you - after the first year it came only about once every 2 or 3 months. Stuck around for a day or two, then I was 'normal'. I'm now about 5 or 6 years down the road (I Think 5) and I'm doing fine. I can handle more anxiety than the normal person, I know how to calm myself in nearly every situation, I am about as easy going as they come. This came after many readings on psychology and the brain (not the bull shit kind of books - the real helpful ones), and meditation, and a lot lot lot of insight.
I can smoke weed now, I can take LSD, I can take shrooms now. I've felt immense amounts of love and happiness. I had blissful days - the whole day awesome.
The internal conversation I wish you'd change to is "Alright - this is going to be fucking tough, but this guy knows, I'll be fine".
And you really wanna know whats odd? I'm extremely glad I had a horrifying trip. It took me about 2 years to finally say that, but I do.
I'll be here for you - we all will.
