Yes
As somebody who has genuine clinical loss of sensation, I can tell you it isn't something you have to self test on or to double check. There's a very distinct pattern that a doctor would recognise, and it comes with all kinds of other issues.
What you're describing sounds very much like anxiety. Your digestive system, muscles and nerves are all feeling the effects of the huge dose of stress hormones going through your body while you worry and panic. This can cause so many strange feelings, especially in err...vulnerable areas! You're spending so much time in mental fight or flight mode, your body doesn't know how to feel. Your system is going to be sending all kinds of panic signals around which will feed into you feeling worse and worse sensations. Remember that the brain is a
very powerful thing.
You really need to start addressing the anxiety, as no amount of reassurance here will help you. We are not doctors, and we are not mental health professionals either. For the most part, we are people who have dealt with or are dealing with anxiety in some capacity and can see when it's overwhelming somebody. You CAN get through this though.
Why don't you make yourself a promise? Tell yourself that starting now, you will commit to the CBT, therapy and anything else that you're doing to address the HA. Instead of posting your fears and any new symptoms here, use the thread to post positive updates about your progress instead. Even tiny improvements count, and bad days don't negate those. Make sure you try to keep a record of the good changes. We all want you to succeed, and I believe you can do this.
