Should I wait it out?

I’m on day 3 of 5mg. I have GAD and depression. My doctor wanted to start me on trintellex and then add buspar after getting used to trintellex. A few hours after taking my pill in the morning I feel like I’m on DRUGs… like that teeth-clenchin’ anxious and energizing coming up feeling when you take acid or something. It’s … not comfortable. I also have tension in my head, neck and shoulders now…. Does this go away?? Anyone else have this?? Sucks getting a new flavor of anxiety when you were already battling anxiety
