Hi @BlueBay,
and hello to @MoonGal as well.
I suffer from anxiety, too. I would guess that it's GAD, because I worry about almost everything. The anxiety feels the same, but the object of my anxiety changes slightly all the time - I would say I also have mild to moderate social anxiety, too.
I worry if I miss a call on my mobile, I worry sometimes about crossing the road, I worry that people don't like me much, I worry about my Dad being alone since my Mum passed, I worry that I haven't given my husband the attention he deserves. I worry about what I'll cook for dinner!
It's like I constantly feel like I'm under pressure and it's very exhausting. It's normal to be concerned about all these kind of life issues - but the level of anxiety I attach to almost everything is way too extreme. Constantly going over things in my mind does not help. It only makes me more anxious.
The thing that helps me the most is to "label" the anxiety as soon as it happens. Rather than directing the anxious thoughts towards an issue - like thinking about my Dad's loneliness - I just say to myself "I'm experiencing anxiety right now." Then I take action. I might make myself a cup of herbal tea and pick up a favorite book. Or I might go for a walk in nature, I might take a shower and then put on a favorite shirt and some perfume. I find it helps to do just about anything, rather than just sit there or lay there thinking.
It's good to call a friend for a social chat, too. You don't have to tell your friend that you are feeling anxious... although it's fine if you would like to do that. Then change the subject and talk about something pleasant.
Something that I found really helpful is to practice mindfulness meditation. There are plenty on on-line resources you can use if you would like to explore this. I think @Silenus has written about mindfulness recently here on SANE forums.
Also, some people find antidepressant medications can work very well for moderate to severe anxiety. I have taken these meds in the past with good effect. Benzodiazepines are also good at relieving anxiety but they are not reccommended for every day use. You would have to talk to your doctor about medication - not everyone needs it and all meds have side-effects. I'm just saying that the drugs worked for me.
I hope you feel better soon.
