You are not crazy. You may be suffering from GAD (generalised anxiety disorder) which makes you worry about, well, pretty much everything!
"Generalised Anxiety Disorder is one of the ‘anxiety disorders’. A person with GAD is in astate of constant anxiety over many aspects of their life - relationships, work, health, familyand/or finances. Just about anything that a person can think about - they worry about.The concerns are ongoing, extreme and unrealistic. The person feels worried and anxious most of the time."
I find with GAD I get over worrying about one thing and BAM! The next thing comes up. It can be health, it can be study, family anything at all. It's annoying, but it sounds like you have a lot going on in your life right now and one of the most important things is to be aware of your symptoms. It's not "just in your head" but you can control the anxiety by using your head, and your body..what tools do you use against the anxiety? Have you tried CBT? I find writing down my worries (journalling) is a great way to help me see how unrealistic some of them can be. It's okay to be health aware when you are pregnant, but make sure you don't become obsessed! I hope we can help you out a little with this. Many of us have GAD here, you are in good company.
This is Kitt. Wow you have a large amount on your plate. Starting nursing school is stressful. I know I have been there and had 4 children at home.
IMHO it seems you are having issues with Health Anxiety and what your learning in school is keeping the topic in the front of your mind.
Before practcing BP/P do they not teach you normal readings.
Health Anxiety: refers to an excessive preoccupation or worry about having a serious illness. Often, health anxiety persists even after a physician has evaluated a person and reassured him/her that his/her concerns about symptoms do not have an underlying medical basis.
Always stay in touch with your physician as we are not professionals.
Bless you and practice staying in the moment...........do not worry about the past and the future will take care of itself.
