Hi everyone, I've been really struggling with my anxiety lately and it's starting to affect my quality of life.  I've always been a functional anxious person, get naturally nervous and anxious about things but normally would be able to work through it.  I'm someone who does tend to overthink things and get stuck inside my own head.  

About 2 months ago I suffered a panic attack at home out of nowhere one day.  It felt like I was having a heart attack and I was shaking uncontrollably.  My partner thankfully works nearby and was able to come home and help calm me down.  Every since then I have been on edge and suffering really bad anxiety.  I continue to have these anxiety attacks where I feel this wave of fear race from my head down to my legs and I start to panic.  This may not happen everyday but I find the more it happens the more frequent they get.  

I have spoken to my GP on this and had a referral to a Physiologist.  It has been good to talk through my problems and I feel I'm much more aware of my mental health, but the anxiety attacks continue to trigger.  As soon as my brain senses something is wrong and I feel a bit off it triggers and I feel like I'm going to pass out.  I was prescribed Sertraline to try and help but that made my anxiety much worse and I had horrible insomnia so came off them to try and work through it naturally.  

I'm looking for advice on how to manage these anxiety attacks.  I can live with and continue to work on the general anxiety through the work with the physiologist and things like meditation.  But the attacks are really knocking my confidence around and I'm living in constant fear of it triggering and not being able to do anything about it or have someone to help calm me down.  I do have a follow up with my GP tomorrow and was going to bring this up with him and possibly reconsider medication.  But I'm worried about the side effects and making things worse.  

Apologies for the wall of text, it helps to write everything out!
