Hi Rachel
Sorry to hear how much you're struggling with anxiety. I'm a hypnotherapist and thought perhaps I could share some information which may be helpful for you so you can make an informed decision. Not here to push my services, don't worry :)
There are different types of hypnotherapy which I appreciate can be confusing to know which approach is best. I would look at a few therapists to see what they offer and explore what feels right for you. Most therapists offer an initial call so you can get a feel for what it's like working with them.
I started exploring hypnotherapy many years before I trained and qualified, and in my opinion I love the solution focused approach. This is what I eventually trained and qualified in. This approach can help train your brain to see your life in the absence of your problem. It draws upon your skills and resources to facilitate a shift in perspective and bring about the change you want to see. It involves a combination of a hope filled conversation followed by hypnosis.
In regards to hypnotherapy over video call this does work equally effective as face to face. It just takes place from the comfort of your own home. Some people prefer this as they're in an environment that's familiar to them and able to relax easier. Others prefer the face to face interaction. It's personal preference but the session format is still the same.
Hypnosis contrary to popular belief is not mind control, in fact it's about you having control. A hypnotherapist cannot make you do anything against your will. The process of hypnosis is to help bring your mind in alignment to focus on what it is you want to achieve.
I would say be wary of anyone offering a cure though! Anxiety is a hardwired response to danger. Sometimes the brain gets it wrong and can overreact which is why it can be problematic when it impacts your day to day living.
I completely understand how hard it is living with anxiety and panic, I've been there. If I can offer you any hope is that the brain is malleable and can learn new patterns and habits. Change is absolutely possible.
P.S. Tip for panic attacks. There are a few things you can do to help regulate your nervous system. When you're experiencing a panic attack you may notice your breathing is rapid. If you focus on slowing your breathing, especially making your out breath longer than your in breath this can help calm your body down. This activates the parasympathetic nervous system (rest and digest state) and the more you practice this the quicker and easier it becomes.
I wish you all the best and I hope you can get the support you need. If you want to ask any questions I will be happy to answer.
Sally
