I too sm a severe anxiety survivor. Med free for about 9 mobths, no therapy in about 6 months. The hormones have been short to driving me nuts to be honest. Did you ever do mindfulness in any of your therapy? Its a lifesaver being pregnant, honestly. Ive been doing loads of it when i feel anxious and its definitely helping. If you haven't def get some resources, its v good. Its so hard when youve had severe anxiety, normal anxiousness about being pregnant puts your body in overdrive and you automatically assume its the past anxiety. You have to allow yourself space to be anxious but keep in check that this is new and normal. This is not 'reverting' back. Its hard but its become like a mantra for me. Everytime i feel my heart rate going fast i have to say this is not a panic attack, i am pregnant, this is normal. Everytime i cant sleep because im worrying i have to think 'i am not having months on end of sleepless night, this is because of pregnancy worries' lol. It sounds daft but saying it to yourself makes it seems a little more believable.
If it becomes a problem i would def say to GP and midwife, esp if yove been to services before they are well versed in helping pregnant women. You wont be the first pregnant woman in that situation. Pull out all your old coping mechanisms that weren't meds. Mine were baths, mindfulness and meditation, deep breathing, reflexology and anything that day that could hold my attention for ten minutes. I talk over names or prams or decor for baby room when i feel my mind straying and panicking. Definitely say to whoever was your support network too, mum, friend, partner just anyone so they can help too. I really do understand the despairing feeling when you feel anxious and you suddenly think, this will be my life again. Its not. Just breathe and take a step back. Its just your brain was so used to dealing with anxiety that some of the residual 'panic' mode is still there, it is preparing because it had to for a long time for an anxiety or panic attack. In time it will diminish but its fairly recent and there is a natural flood of anxiety through pregnancy which your brain is just trying to interpret in the only way it knew how.
Remember small anxiety is normal, dont supress it but dont panic, allow it but control it. Write everything down or talk everything out even to yourself. You are the one in control now, remember that
please message me if you need anything, youre not alone, i promise you, things are different now
