hannah99, hang in there but reach out to your doctor if it's getting really bad, ie thoughts of self-harm. I believe it can take 4-8 weeks to get used to these kinds of meds and start to see the benefit. Or, this prescription may not be the right type or dosage for you. There's trial and error, but doesn't mean it won't work for you. Keep an eye on it and keep working with your doctor
I have used them in the past when I was involved with a sociopath. What they did for me was get me out of the fog that my racing thoughts created, so I was able to think a bit clearer. I wish I accompanied them with a therapist back then, I hope you are! Edit: and yes give it some time to kick in.
I rushed to reply, apologies!I'm just now reading that you are in therapy, great!
