I’ve always been an anxious person, but have managed to deal with it relatively well but two years ago I had really bad anxiety for two weeks that ended up with me getting put on citalopram. Things got better, I was bad at remembering to take the medication and eventually stopped altogether and had no more issues until recently. 
  
For the past few months, every so often I would get a feeling in my head and in my arms/legs that everything felt very light, weighing nothing. This happens most when driving and recently going on a walk. 
8 days ago I had my first panic attack. I was walking and started to feel weird in my head and my body felt like I wasn’t moving it and over all just really off. i didn’t actively feel anxious, and was just having a casual conversation with my friend but still had a panic attack. I walked myself out of it and felt shook up but fine the rest of the night. 

The next day I woke up feeling fine, went and got food and left to go to my parents house. 20 minutes into the drive I had another panic attack (the same feeling where my head felt off and my arms and legs went light) I had to pull over and get my parents to pick me up because I was so panicked I couldn’t drive. I had two more bad ones that evening and haven’t had another since. I have been feeling anxious because of it, but now my head is my main concern. When I’m lying down the feeling doesn’t seem to be as strong, but when I’m up and moving my head starts to get worse.  I don’t feel dizzy or weak but I feel like I could fall (even though I know I won’t) my ears are also on and off feeling blocked and pressure filled. 

Long story short I’m trying to figure if this sounds like it’s anxiety causing these feelings or something else. 

My other options are stress that comes along with a lot of things happening in my life, an inner ear or balance disorder, or I also suspect I have inattentive adhd and wonder if that could be causing my anxiety and it is coming out in this form. 

I know that’s a broad range of ideas and I’m not trying to self diagnose just looking for some other thoughts. 

To note: I’ve seen a doctor and have been put back on citalopram, but have heard some people say to check about adhd before taking an ssri to try and fix things.
