Dear Welcome to HCM We understand your concerns I went through your problem description. I suggest you not to worry too much. This is not the memory loss. You are being overly stressed and body is taking the toll. From the description it is very clear that your lifestyle is not at all suitable for a human being. Human being need to arrange life between work and rest. There are lot of examples of people losing their temper if not followed this schedule. I don t know what course you are taking. But I can assure you, psychologists, through different studies, have constantly pointed out that a person should not read and write academic matter for more than 4 hours. He need sleep for 6 hours at least. Leisure time activities for 4 hours. Workk for 8 hours. 2 hours for food. During the work he can learn practical lessons and take notes, but not studying from book. Smoking 20 cigerettes a day and masturbating daily is also extra stressful. Therefore I suggest you to change the lifestyle as I suggested. You can have a telephone counseling session with me. For that contact www.healthcaremagic.com, customer service executive. Hope this answers your query. Available for further clarifications. Get well soon.
