So I’ve been on both Venlafaxine (I’m from uk but I think it’s called Effexor for Americans I think) and Quetiapine (Seroquel) since I was 18. This was to help me with my multiple mental health diagnoses (one of which being BPD)  after being admitted to a psychiatric hospital for three months. 

I think both medications have treated various symptoms and helped me calm down a lot. But I am now 25 I and I have lack of energy and motivation to do anything and my emotions, imagination, and sense of self, feel dulled and muted. I feel like I just exist as a shell completely numb to most things. I even find it hard to cry.
That’s not to say I don’t have really bad BPD days and extremes it’s just different now. 
Has anyone else had experience of this? Is it the meds or is it my clinical depression? I really can’t tell.
