Ditto on all the above, I know how much you want to just be back to 100% but it takes time.
I could not stand the brain problems in the beginning, was always active, think mountain climbing and hiking so being told to calm down and rest was pure torture, I learned the very hard way to get a lot of rest.
Your brain needs time to heal, others who have never experienced this just don't get it, they can think we are lazy, it's not the truth at all.
5 weeks is SO new, I was suffering so much last year I thought of ways to do myself in, rest, rest, rest...you have to do it for yourself so you can begin the road to recovery.
Also, for a long time I questioned everything, when will this be better, what if it never does, what if's all over the place and made myself worse. I had the most severe headaches that just would not budge.
I know you feel so alone, I do too, a lot of us here do but you have us, we all understand so you are not alone, this forum has been a life saver for me and others.
Keep posting, keep reading the other posts, and most of all don't be hard on yourself at all, I know it's hard.
Don't over do things, if you can go for a nice walk don't over do that either, you can tell if you are.
Hang in there,
