Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not too worry much. You are right. CBT makes people relaxed. People feel relaxed even in stressful situations. But there is nothing negative in that. It cannot alter your reflex system. Reflex works as fine as before. Only change takes place is to the thinking and perception process in anxiety situations. The production of stress hormones during peace time reduces and thereby the body reacts relaxedly the stress. You can do energetic and agile activities like games to increase body reflexes. Post a direct question to me and I shall prescribe psychotherapy to you to help you. Hope this answers your query. Available for further clarifications. Good luck.
