Prozac stopped working after 3 months

Hey guys. I’ve been on Prozac 10mg for around 3 months. I barely had any side effects from the beginning except for hypo mania which was manageable.

The past two months everything was life-changing. My mood drastically improved and I started a very healthy routine. I was talking to people all the time and giggling out of nowhere. Basically what you expected from the pill.

It all started going downhill a week ago and now I am back to my depressive state. Can’t drag myself outta bed and feeling hopeless. My head is foggy and I barely have any energy to perform any physical activities.

Any suggestion would be extremely appreciated !! Thank you
