Congrats on 2 weeks Achelus!
You can do this!
At 2 weeks, your brain chemicals are trying to re-calibrate to normal and people can feel down during this period. Get through this and you'll never have to do it again. Days 10 - 20 were the hardest for me too.
Eating well and exercise (even just a study walk) will make a huge difference in how you feel and help the brain rebalance more quickly. Think of them as little acts of self - care.
