350 days no PM, mood changing

Hi guys. During my journey I was mostly depressed, in flatline, feeled alone, no motivation etc... But Before 2 weeks now, I started to feel really awesome for about 1 week or more, then now I feel horrible again without any reason. I have read a lot of things in forum, and people say that during reboot its perfectly normal that the dopamine level goes high and down, but I have this thing just now, after 350 days. Is this normal? Can be the reason of this, because I was a huge addict (3-4 per day) and I can see this thing as a mark of the healing?
