Welcome Trying2Quit -
Congratulations on your week sober! Everyone's withdrawals are different, but I can definitely relate to the tiredness - it took a while to get my energy back. I also had insomnia and night sweats. The anxiety and depression started lifting after about a week.
It's definitely bumpy at first. I'd have a good day, then a bad one, then another good day, etc...... it didn't get better all at once. In fact, I was still noticing positive changes even after a year sober.
Take it a day at a time and be patient with yourself. It really does get better!
