I used to have thoughts like that, but with the right meds and therapy they seemed to go away. Remember it is just a thought and you do not have to act on it, nor dwell on it. Observe the thought and move past it. Doesnt sound like psychosis or akathisia but Im no doctor (yet).

The meds can take up to 6 weeks to be effective, it is not that long in the scheme of things. Try not to diagnose every symptom, just let them be, observe and wait it out for a few more weeks to see if these meds are really going to work for you.
