This thread has provided good reading over the past year or so, although I'm a long time lurker I thought posting my experience may help others that are just reading as well!
Back in January 2020 I had a panic attack in the back of a taxi after my normal trains home from work were cancelled due to bad weather. At the time it did not feel like I was going through anything particularly difficult (loving wife, well paid job, close friends and family). My wife had been in therapy for about 6 months at the time due to anxiety and so I was aware of the benefits of therapy, the 'journey' and what it involved. I didn't need much convincing after having a panic out of nowhere to go and get some help, I went to my local GP and asked for a referral for a therapist. I'm extremely fortunate that my employment provides private medical insurance so after calling round a few places I found what felt like a suitable therapist and attended my first session in the middle of Feb 2020.
Boy, what a journey it's been since then! Therapy has been one of the most challenging and rewarding things I think I have done in my life, the first few sessions were extremely difficult, dragging up everything from life decisions to my childhood and everything else inbetween. It soon became obvious that although I give the impression I am 'fine' to the outside world, inside I am generally a fairly anxious person. It's been fascinating to understand how my parents getting divorced when I was a child has impacted my relationships now and specific situations that end up making me feel anxious.
I am (of course) in no way completely better and quite frankly I will always expected to be anxious in life, but as others have said in this thread, having therapy makes me feel equipped to at least deal with these situations when they arise. I'm finding I am opening up myself to more emotionally difficult conversations with my wife, being more open with my friends (rather than giving the impression everything is fine) and to be more considerate of others. I've tried to not become too preachy to colleagues and friends but attending therapy has become one of the better decisions I have made, I've had about 16 sessions in total and now at the stage where I will reach out to my therapist if I feel I need a session (rather than having them scheduled in). All in all 10/10, would recommend.
