You do have something in your brain that is making you feel this way and it is quite simply - fear. As I have said to you before, a major fear when dealing with anxiety is "going crazy", and as I said to you before, if you were going crazy you certainly would not fear it! You are dealing with a very heightened sense of anxiety and whose brain wouldn't feel confused, foggy, and out of touch given that? Now as to the question about if you had ever had a head injury - let it go. What you are doing is running around trying to find answers. The problem with that is that it is easy to latch onto the scary stuff and let the good stuff go by you. Why? Just your fear at work again. Fear, fear, fear. I can not say that enough.
It is not as simple as calming down and relaxing. You need a program to help you do that. That program must first come with understanding of what is wrong so that you can accept that. Then you can move on to helping yourself feel better. I have mentioned time and time again Dr. Weeks. If not that, then you need to stop researching what could be wrong with your brain and start researching dealing with anxiety. Once you understand that the things you are feeling are very, very common in people dealing with anxiety then you can begin to relax a bit. Research anxiety on the web. Go to amazon and look up helpful books. Go to your library. Look into books by Dr. Burns, Shirley Swede. Cognitive behavioral therapy is the thing most recommended for anxiety. Research people who deal with that. The most important thing is that you find a book or someone you can believe in and trust. The more you research, the more you understand, the more you realize this is normal given your circumstances, the better you will feel. Simply worrying and fearing is not good enough anymore. You have to tell yourself that you are going to find the answers, you have to tell yourself that you can do this, you have to tell yourself that you will get better. Is it possible to afford a psychologist who deals with anxiety. Most therapy for this is short.
I don't mean this to sound so harsh. Trust me, I do understand and that is why I hear what you are saying and know where you are. But, I also know that until you take steps to get better that you are going to stay stuck. I know that there is nothing seriously wrong with you - no brain disease, no injury, no going crazy. You are simply scared. You are NOT going to go crazy and there is NO disease eating away at your brain. AND, you WILL get better. You will get better when you make the decision to do so. You will get better when you begin to fight and stop letting fear stand in the way. Is it easy? No. Does it take time? Yes. Is it possible? It is more than possible, it is probable when you work on it. This requires work, just like raising your son does, but work brings good results.
Another thing to do is to counter every negative thought with a positive one. Your mind is believing what you are telling it! So start telling it better things. "What if I go crazy". Counter that with - "I am not going to go crazy. That is just my fear talking". "I don't feel connected to my family." Counter that with - "Well, of course I am connected to my family. I am dressing my son, feeding him, kissing him goodnight, talking to my husband. I may feel spacey and I might for awhile, but I am connected with my family." How about - "My brain isn't working right." Counter that with - "Well of course it is. I manage to write a very intelligent posting on the boards. I explain my problem very well. I am running my household. I am totally in touch with myself, my feelings, and my surroundings. It may feel weird, but it will pass one day". Instead of fear, put in its place - hope. Even if that is fleeting for awhile. And more importantly, put in its place reality. Remind yourself over and over and over again how really very good you are doing.
You are not the first, nor will you be the last to feel this way. Volumes have been written on it. Take heart in that. Mostly take heart in the fact that these people did not go crazy nor did they lose their minds. Pick yourself up, research, find good answers, not scary ones, and get determined to get better. Be determined to get life back. Be determined. It is definitely in you just waiting.
