Yes, you can come out of it.
I've felt it before and came out of it.
It took a while but boy am I glad I climbed out of that ditch. I hated every minute of it and I will never go back to that dark place again.
I say this to you to let you know that it is possible to get better.
One day you will see the faint resemblance of a pathway toward getting out and you will set on this path.
And from there, you will begin your journey from darkness to light, and then you will experience happiness again.
Like I have.
