Of course it will go away. Our bodies are ALWAYS in healing mode. The natural process is to heal and not shut down.
Keep your body and mind sharp with exercises (reading, games, puzzles, therapy etc) and keep the body strong with exercise and clean food and you will get better.
I'm in the same boat as well. My anxiety and depression overwhelm me, and I just feel like throwing in the towel and laying in bed FOREVER, but you need to learn to ignore these sensations and know your perception is unbalanced right now. So like a nagging friend, tell the negative thoughts to take a friggin hike
You'll be ok
The world breaks every one and afterward many are strong in the broken places
