Welcome to the forums, Mia.
I'm with you, the overthinking that comes with the anxiety territory is exhausting. Being dragged helplessly where we don't want to go makes life difficult, not only for ourselves but also for those around us.
Explaining is hard...because anxiety doesn't make sense. It happens outside the scope of reason and logic.
Being a medical condition (as opposed to the passing state of feeling anxious), it should be regarded and treated as such. I suggest you do the K10 test (top left of this page in the Facts section). You will also find relevant info in the drop down menu.
Booking a long GP appointment would be a first step towards helping you manage this distressful situation. Unfortunately, anxiety doesn't disappear of its own accord. If left unattended, it can easily infiltrate every area of Life. No need to struggle alone or feel embarrassed because you are not coping. It is something happening to you but not caused by you. So please take good care of yourself and do not hesitate to reach out for the help and support you so much deserve.
Your partner would be given the opportunity to go along to an appointment and learn from a pro point or view what it is you are up against. He would then understand you better and support you better too. This approach would burden him a lot less than not knowing what causes your emotional turmoil, leaving him to feel helpless and bewildered.
In complement to medical help, you could check out coping strategies like mindfulness, Relaxed Breathing, Relaxed Body Scan etc... Smiling Mind and Buddhify are useful apps. Of course those techniques are only efficient if practiced regularly, preferably when all is well. It will then be easier for the mind to slip into a calmer mode when most needed.
Please feel free to continue to talk with us and let us know how you go.
Good to have you on board.
