I think my antidepressants are making me overall feel worse

For context, I got prescribed exuber 10 (due to my age, I think? Or simply because the dosage is low) after attempt last march. I’m off it right now, but while I was taking it, around 4 weeks(?) I believe. But it’s made me feel so much worse, I feel dumber, I get sudden bursts of happiness, if not, then I simply feel miserable. Overall, I think its made me feel less like “me”, before I even took it. If that makes sense?

Then there’s the part where I can’t for the life of me hold on to friendships like before, like I feel nothing. Loss of interest, etc. Overall it’s been like hell for me.
