Hey there. Welcome to the forum!! Thanks for reaching out. Anxiety knows no boundaries and can get 'anyone'. Even those who never suffered it before and those who have relatively peaceful, successful lives. Everyone gets anxiety from time to time. What makes it a clinical diagnosis is when it begins to impact daily functioning. The more it impacts it, the more it becomes a clinical problem that needs treatment. Many can overcome it by simply applying coping skills and lifestyle changes. Thinking in terms of if anything triggers it. Thinking in terms of if it is over 'real' things that you can problem solve about or just ruminating and at times illogical compared to the reality of the situation. Are you stressed and pressured? I had a psychologist tell me for the average person not suffering clinically, that anxiety actually serves a purpose. It is warning you but also just notifying you that something is really important to you. It's a lot less troubling when I think of it that way.
This sounds like it may be or about to be impacting your job. Like you are getting the feeling of wanting to just close down when the anxiety hits. If you DO start closing down, then it is time to address that for real so you do not lose your job.
Here's a nice tip list of things to try to help yourself: https://adaa.org/tips copy and paste that. It has some very simple things to do including working in relaxation/decompression time, proper sleep, eating healthy, eating regularly, exercising most days, deep breathing, meditation, counting to 10, etc. There is an app I personally like too called Calm which does guided meditation and my son uses Head Space. Both good apps for self soothing through anxiety. There is also an interactive app (probably several of them by now) called Youper that you get feedback that is based in things like CBT and it kind of talks to you and talks you through some of these feelings. I really find it kind of cool and helpful. I think it was free, I can't remember as I've had it for awhile. Head Space was free and I do pay for an upgrade to Calm for myself but they have a free version. My other thing I do for anxiety is to break things down to smaller parts and just tackle it one at a time with small goals instead of the huge looming goal that feels overwhelming.
If it gets to the point that you aren't functioning very well, you may look into talk therapy. It can be really helpful to sort things out. Lots of therapy is done as 'telehealth' making it much more convenient. So, that could be an option for you as well.
Hang in there. There IS something to consider though which is the toll that long term anxiety can take. It builds and I just say to you to not let it get to that point. Work on it now so I'm glad you wrote here and I hope we can stay in touch and continue to help one another.
What you describe sounds more complicated than just your job, as you mention some difficult with your folks and so there's also that. If your folks are having problems and you're isolated from them and you're adapting to a new job, that would be stressful for anyone, but stress isn't anxiety or any kind of mental illness so it's impossible to say from what you've said if you have a mental illness or not. You're definitely not describing OCD, so you can put that one aside. Another difficulty is that a lot of people get promoted to a job that doesn't suit them. There's even a name for this, though it usually involves competence. This is also not anxiety, it's you now being in a job you don't like and didn't want and you're reacting negatively to it. This could be anxiety about your ability to handle the new level of responsibility, which is a form of insecurity that would probably pass with time as you settle in. If you're a fan of any pro sport, I'm sure you've noticed that most athletes take some time to reach their level because at first they're anxious about succeeding. It takes some time to get settled in to anything new -- most of us has some problems at some point in school when we advanced grades, then got used to it and then it was just easy for us. So lots of possibilities that aren't any form of mental illness but just part of who you happen to be. What you have to figure out is, given you say you enjoyed the role you had before and didn't want this role, is whether you're feeling insecure about ability or it's just something you don't enjoy and it's making you miserable. That's not east to parse, but it's something you do have to figure out. Companies promote people to positions they don't want to be in all the time, and also promote people all the time to positions people aren't really good at. It's just how they operate. Time will answer that as you settle in. If it is anxiety then you would probably have noticed anxious thinking before this event happened. Whatever you label it, however, you're in the position now, and your choices are to make it work, ask to be moved back to your comfortable place, get a different job with a different company, or if it is anxiety forming find a therapist that will help you overcome it. Peace.
