Good post.
I struggled with severe anxiety (GAD) for most of my life until about 5 years ago. I've only had one panic attack and it's when i was in high school.
They had me on meds for 2 years and it helped some, but the best thing i did was to learn how to "let go". Of everything. It wasn't about death for me, most of it was about work and social requirements. What society thinks you should be and do. Once i learned how to manage the triggers and let go of things it all became better. But it took years.
In my 20's i worked a high stress job for a huge engineering and construction company. I was pushed to the limit every day and treated like a slave. Everyone was working 60 hours a week and treated like shit. It bothered me because i liked my job but hated the environment i was in. I wouldn't sleep at all and had severe struggles with anxiety. I'd get so anxious that i'd freeze up and couldn't function for hours. It was terrifying.
I also struggled with social anxiety my entire life and still do. Going to a psychiatrist helped, but not like people would think. What i learned is that i do have social anxiety and i'm claustrophobic, which is a bad mix. Loud crowded places drive me insane, literally. I also learned that i'm an introvert and don't like people very much. So i enjoy my time alone more than time with friends and family. Knowing this helped me realize how to control certain situations and that prevented a lot of anxiety problems.
About 5 years ago i was in a bad place, very upset at the world and hated life for the most part. I always wondered why? So i took a month of work and traveled to Alaska for 3 weeks, staying in a small town. Over this time period i basically rebuilt my mental state of mind. Read a lot of books and focused on what really matters. Which is being happy with YOURSELF.
What i learned is that nothing really matters except your friends and family. Work is not important and what society thinks of you means nothing. 99.99999% of the people you meet will never be a part of your real life, so fuck them. Do what makes you happy and stop worrying about your boss, projects, people and expectations.
I set my expectations so low for everything that i get surprised more often, things are better because the little things matter more. Work and go home on a normal schedule, it will be there tomorrow. Fuck your boss and random people's expectations. Learn to not care what people think about you and speak the truth, be honest and don't feel bad if people disagree with you.
Today my life is great, i have no worries and every single day is like vacation. I moved out of the big city because that was contributing to my anxiety. I live in the mountains and work a normal 8-5 job in engineering and development for a small company. I save money and have enough that i never worry about that either. Money can cause a lot of stress and causes people to become evil.
I do what i want and if someone has a problem with that i don't care AT ALL. It's almost funny because sometimes i'm in a stressful situation and people wonder why i'm so calm. It's because it doesn't fucking matter and will be forgotten in a few days. Just let that shit go.
Last year I was in a meeting with the owner of my company and we had just gotten fired by our biggest client because the owner was lazy and didn't respond to the client fast enough. We lost millions in future projects. Everyone at the table was red faced mad and yelling at each other, playing the blame game. I was just sitting there waiting for the meeting to be over. The owner asked me why i was so calm? I said because there is nothing we can do to change this and we should just focus on finding a new client. He was pissed! I asked him why he was mad? It was his fault we lost the contract. That didn't go over well but he respected me for it a few days later.
Fast forward 6 months and we secured a new contract with another big developer. Life was fine! We didn't even have any money problems, they just caused panic about it. Waste of time and energy. Fuck em.
So i learned this simple trick when something bothers you.
Can you do something about it RIGHT NOW? If you can, do it. If not, let it go.
Sounds too easy but it helps me stop dwelling on shit. If i can change something i do, if i can't, i just let it go and focus on something productive.
Anyway, i hope people can learn how to deal with it. I did and i'm a better person. But i don't care about most things anymore, which may create other problems down the line i think, primarily with relationship with my GF, but that's a completely different story.
Also learn to meditate and study Buddhist teachings. It helps i promise.
