back pain... anxiety??

So I was diagnosed with depression and anxiety in July, and I was put on mirtazipine. As of right now, I’m on 35mg. Anyway, it’s seemed to help with the depression, AND anxiety, however I still very much have anxiety symptoms. For example, about three or four weeks ago, I was having bad chest pains. They went away in a week. And then as soon as they went away, I had shortness of breath. It went away after two weeks and came back. It finally went away last week.. but I’ve been noticing I’m having back pain and body pains. I know it’s a symptom of anxiety, but I’m so worried that it has something to do with my heart. I had it checked it february, I had two echos and three ekgs, and a chest X-ray. All normal. I had blood work done last month, all normal. Could my anxiety be causing my back/body pains??? Also, sometimes when I’m too focused on my breathing, it kinda hurts to breathe?? Like my lungs hurt a little bit? But it goes away when I stop thinking about my breathing. Anyway, I’m 15, never smoked or drink, healthy, and not in the best shape. 

Anxiety is a funny thing, as people have this tendency to believe that to suffer the physical symptoms of it, you have to be feeling anxious along with it. Let me tell you right now, I got the worse of my physical symptoms in all my time struggling with anxiety when I wasn't even feeling anxious. I was watching telly. Perfectly calm and I had a panic attack. That started a cascade of health concerns with me ranging from palpitations, heart and chest pain, breast pain, nausea, pins and needles, numbness, neck pain, low immunity, etc. Etc. I really could go on. Point being, it's a fickle beast and it's only by accepting it's anxiety and working to retrain my thought process when I do get aches/pains etc. that they've eased off. But I swear for two years it was like my body wanted to try out every little thing going just to text me haha.

Sooo weird right? Doesn't make sense me either but let me assure you, if tests are coming back normal, you're fine. X

Omg I'm same as caz19600 haha. Ever since I've mentally been feeling better, I've been feeling worse physically -__- lol. When I was mentally anxious, I would get the occasional racing heart and I would just feel sad and nervous all the time.

But now, I feel completely fine mentally, I'm in a good mood, I don't get the racing heart feeling, etc. But now I get chest pains, bad muscle tension in my neck/head, headaches, dizziness, all of that. It's sooo frustrating bc It's like I DON'T FEEL ANXIOUS!! Lol why am I having all these physical symptoms?!

My therapist says this is a "subconscious anxiety", and basically my body is so tensed up from being anxious for so long, that even though I don't feel anxious mentally at the moment, my body still does. -___- so annoying.

I think you're completely fine, it's just same as me and caz19600. Those physical anxiety symptoms can be a real pain in the butt. I've been dealing with them for about 7 months I'd say.
