When you start noticing a positive change from where you were. I suggest keeping a journal or using daylio, it's what I use to keep track of my mood

In fact, my family notices that I'm progressing before I do. When they see that I have excessive energy or increasing speech, they tell me that I need to see a doctor.

You may notice that your energy is up without the downs after - a more balanced feeling. Maybe you will be able to do more in a day or get to do tasks or desires that before you didn't have time, mood or energy for. Also the ability to keep in touch with others should improve. Wish you all the best, most importantly be patient with yourself.
