After a lot of traumatic life-altering changes happened to me, I was for years described anti-depressants (paroxetine), (which I still take in a low dose) and two different benzodiazepines (temazepam and oxazepam), which I stopped using. My question is, if the meds could have made me quite numb to spiritual and paranormal experiences.

Any experiences of answers would be very helpful

I don't think the answer is important, because physical and mental health always come first, and I see a lot of potential for problems with this kind of topic here. If a person is prescribed medication by a medical professional, they are advised to take the medication for the reason it was prescribed. The paranormal is not a substitute for this, and should never be a reason to stop medication(s).
