General

Have you talked to your doctor about changing them ? probably a stupid question but I just know my mum is on effexor and she doesnt have any like dulling of other emotions

It's possible that the medication could put a certain dampener on emotional engagement, especially if you're feeling a lack of emotion while on them already. My own medication tends to just make me feel very serene whenever I'm on it and tends to lower my own emotional engagement, though I don't really feel it inhibited me that much.

Anyway, don't worry too much about it overall, it should turn out alright. Like Justin said, just try and adjust to the feelings and get used to the new state, that'll help a lot.
