Sudden GAD, looking for recognition

I would like to share my story and am looking for some recognition.

I’m 34F, married, kids, a job, friends. Until 3 months ago everything was fine, I was happy, living a very busy life. Until one day, out of the blue, I had this feeling of panic coming over me. This was the first time I ever felt like this. I couldn’t really figure out what was causing it. The next days this feeling stayed, I told my husband it felt like I was going crazy. I took some rest for a week and felt sort of okay. I went back to work but after 1 day the panic and anxiety returned. I felt like I totally lost myself. I went to my doctor and she said this happens a lot with women my age, I’m burned out. I got to stay home from work ever since (we have very good insurance in my country). I went to therapy and got a lot of rest. I had some days where I would feel a little bit like myself but eventually I spiraled down a vicious cirkel of constant worrying about my situation, more anxiety to a point where my body just was in a constant state of fight/flight. My therapist thinks I have a GAD. One of the worst symptoms was not being able to eat which caused me to lose almost 20lbs. Of course this made the anxiety even worse. My doctor decided this couldn't go on any longer and prescribed sertraline. I’m now on day 8 of 25mg and it’s been very hard for me. I’m very nauseous so eating is still a big problem. Also since yesterday the anxiety has gotten really worse. I know I have to get through this and hope to get the positive effects soon. It’s so important that I regain my weight since I’m severely underweight now. And I want my life back!! Being able to take care of my kids and just enjoy life again.

When I read other stories here on Reddit, most people seem to have a long history of anxiety and/or depression. Although I can sometimes be an over thinker on some subjects, it hasn’t really affected my life in a big way before. I’m wondering if there’s more people out here who are suddenly hit by this awful change in mental state? I hate that I’m on medication now and everyday wondering if this is the right thing to do… Hoping to read some reassuring reactions.

Thanks so much for reading!
