I am 39. I go through spurts of low energy and low motivation. I can get lightheaded, and find it hard to focus. Over the past 2 years I have had 3 episodes where I lost equalibrium for a few seconds, and remained lightheaded for a day or so. Very strange, and I had great health and energy my whole life. Nonsmoker, in shape...What s going on?
Degree understand your concerns went through your details. I suggest you not to worry much.  You are 39 and you are healthy. Very good. Have good healthy habits. Very good. The symptoms you are providing may not be of losing equilibrium. Could be more of cold related. We do have all these symptoms throughout our life. During our young age, we just ignore. When we get aged, we notice these. Any way to be sure, please visit a physician. Psychotherapy techniques should suit your requirement. If you require more of my help in this aspect, Please post a direct question to me in this URL. http
