Happiness, worry and anxiety, also stressful job .

[Perplexedaschips]

I have written this here rather than in mental health as I don't think my problem is serious enough to warrant actual treatment etc
It's more an emotional health/ personality/ happiness issue that I am wondering how to deal with.
I have an extremely stressful job. I suffer with occasional anxiety although the rest of the time I am happy and settled. I do have a mildly obsessive nature and have tested highly on the scores for highly sensitive personality.
I first noticed a mild anxiety when I had trouble settling my youngest child at school, some six or seven years ago. When I picked him up I had a feeling of dread until I saw he was ok. The rest of the time I was fine.
Now, I cope well with work and enjoy the challenge. When something very upsetting happens as it does in the nature of my job from time to time, it can stay with me and I feel upset and worried for a few days.
I am about to change jobs within my organisation. When I went into work yesterday to do some admin, I was worried I would see my previous boss with whom I have had a minor dispute over leave. When I went in, I felt very very nervous and anxious. I quickly did what I had to and left then at home felt ok.
I know my job helps me to grow and develop personal skills and am overall more confident than before I was in my ft job, but how to deal with these bouts of nervousness, tendency to take things to heart and worry.
Do I just distract myself and try to see the bigger picture, or am I fundamentally unsuited to such a stressful and sometimes distressing job ?

Hoping for guidance as to what to do when I feel like this and how to become less nervous over the longer term.

Can you try to recreate that holiday feeling of literally-nothing-to-worry-about for smaller periods of time? Perhaps that is what the Mindfulness can do - make an hour in a park playing with the kids feel like an hour holiday from your life. I bunked off for a day out with my Mum recently and genuinely felt like I had been away for a week!

Mm I like being in charge to some extent. But must admit its hard to do tea every night, clear up every night, buy all the food shop do the school runs and organise house things like quotations for things, but in a way it's just how it happens because dh isn't a very energetic person or very organised. He does have a good income though.

Shutup. It's also really hard to do all the home stuff..I did that for a while and it was really hard with very little support from a partner who works very long hours.

Update

I am much calmer since I took some leave. I was quite stressed and overwhelmed before that. I am also pretending to be the person I want to be until I am fully that person....positive, calm, pro active, friendly a good leader and team player.

And I have taken up gardening.

I do think having a hobby helps - the mind space that you get when in creative flow definitely helps with general emotional calmness. I used to sew a lot and could get into quite a zenlike headspace for an hour or two. When I let that time go, it is another factor that adds to anxiety.
