Hi Bella,
Everything you are feeling is normal, from my own personal experience. Your body is going through a lot of changes at the moment. The brain has to learn to function properly again without the aid of what we have all been taking. That can be a different process for everyone. Take every day as it comes and I promise that eventually you will start improving every day. Tiredness and fatigue is normal because we aren’t giving our bodies that “shot of energy” that we would have usually have given it with the opioids/drugs. Returning to normality is a long process but one that I am sure is going to be more than worth it in the long run. Keep going strong and doing what you are doing because you are doing great!
