Welcome to NeuroTalk.
It sounds like you have not given your brain enough time to heal. It needs quiet rest. No loud sounds, busy visual images, socializing with multiple people talking or other excessive stimulation. If you want to get back to your studies and a job, you need to take the time to rest your brain.
When you can go two weeks without any symptoms, you can start slowly adding activities. Try adding one activity and wait a day. It is not uncommon for over-stimulation to feel OK but cause symptoms to flare up the next day.
You also need to avoid caffeine, alcohol, MSG, artificial sweeteners (aspartame, Nutrasweet, Equal, Splenda, sucralose) high fructose corn sweetener and trans fats. Natural sugar in moderate amounts is OK.
There is more I can add but this is a start. If you give you brain enough quiet rest, it will slowly start to heal. I can post a list of good brain nutrition to help too. Check my post under "New Here, Hello" by patty.
My best to you.
