The good news is that this will improve and heal, and you will learn to cope with it while it does. It just seems like you won't right now. That's the good news. The bad news is that the brain can take quite a while to do so, but don't panic and worry. Stress makes you heal slower. Your healing will go through a natural process while your brain recovers. Things that will help you are staying calm, taking supplements like high dose of good quality krill oil, coconut oil, a mushroom supplement called lions mane and high quality vitamins. Your diet matters more now as your brain is in a sensitive state while it heals. Keep your diet good with fruit, vegetables and good clean proteins. Avoid junk food, sugar and definitely sweeteners, alcahol, smoking and recreational drugs.

Learn what triggers your symptoms, everyone is different. The less you trigger symptoms, the quicker you'll heal. Don't overthink what's happened, it's tempting and can become obsessive, try not to fall into that trap. Concentrating on symptoms can and will make them worse. On good days don't over do it, you've probably not recovered until you're symptom free for a good month or two. Overdo it and typically you'll pay for it a day or two later, the brain has a symptom lag which will hit you after you've pushed too hard.

Exercise if you can, but only lightly to your tolerance level. The brain is energy hungry, and if your body is using energy, your brain will struggle in its injured state. Write stuff down if you're struggling with memory, this will improve with time, as you recover, light stimulation will help, but only little by little. Don't overdo it. Get help, if you can't work or pay your bills, make adjustments in your life from any support network you may have. Explain to them the situation as best you can. We all need support sometimes, I've learned most of this the hard way.

Be kind to yourself, be patient, this could take months but may not. Don't worry about time scales too much, you'll get yourself back, it just takes time. I wish you a speedy and good recovery.
