Need hope! 18 days CT

Quick backstory . My husband died and I used kratom stupidly to cope. I knew it was wrong but it got me through. I would go up and down from 2-4 extracts shots for four years a day . Starting getting serious anxiety what it was doing to my health so I said enough is enough. I had tried to quit a few times and knew it was going to suck. I am day 18. Rls is gone I'm able to sleep a little better, but now my only issue is feeling absolutely drained to the point where I have sit down after I do the smallest activity. It's so hard to function. I was praying it would be better by the 2 week period. I just need someone to tell me it will get better and my energy won't be like this forever !

Also I did go to doctor (had massive anxiety) thinking I'd get really bad news . My thyroid is off (I have hypothyroidism ) slightly dehydrated and low vitamin D. Taking All the good supplements and increase my thyroid meds hoping it's just a perfect storm of withdrawal and that stuff! But please anyone have experience when your energy finally shifted ? I don't care about the kratom anymore I just want to function regularly. Thanks for reading.
