No mood improvement 4 weeks in

Im 4 weeks in. 1 week on 150mg and 3 weeks on 300mg. I really dont feel any improvement whatsoever in my depression/mood/negative outlook/sadness.

I talked with my psychiatrist today and we decided to give it 3 more weeks before maybe trying something else.

Im skeptical on if anything will change in the coming weeks. I see people saying they had crazy changes in weeks 4-8 and I want to be hopeful but im just not and im getting exhausted from my constant low mood and negativity/depression.

I havent had any crazyyyyy side effects, some anxiety and overly emotional moments in the first week or two, but thats kind of faded and now i just have decreased appetite. other than that i just still feel flat/foggy, unmotivated, and just depressed and sad.

I know its different for everyone idk what im here to ask... I guess I just need some encouragement or hope that it might get better in the next 3-4 weeks maybe.

If nothing changes my dr mentioned maybe trying viibryd.
