I'm glad to see you back FD
I think you should really address any medical queries you have to your Dr - it might seem like a nuisance or a lot of bother but it really is in your best interests to speak with them, I think.
I think most of us find life strange and maybe even a little empty after we quit.
Give it time tho - we drank for years - you've only been sober a couple of weeks - the fatigue and the unfamiliarity will fade and you can start to think about doing things to fill your life up again
It's normal to feel panicky and maybe even sad about not drinking. I found it easier for me to just focus on not drinking today - that was achievable for me - and repeat again tomorrow
Apart from us and your counsellor are you thinking of any other support?
