On my third month of starting Pylera antibiotics , more precisely right after taking three combination of antibiotics for my H Pylera infections ( since the first round of antibiotics didn't work ). I started to have insomnia and sudden weight lose followed by immensely sadness. And changes in menstruation and continuously low mood and low energy. Now it's been six months . I still feel the same. Although there is little improvement in my sleep. What should I do ?

Ps: I can't find a any reason behind this depressed mood . As nothing changed in my life. It was as good as before.
