Are these problems curable? Curable?

Hello doctor I'm facing these problems written below. Please let me know, are these problems curable? Also, suggest the diagnostic test if required. I'm stuck during the talk and afraid in hostile situations (like fight etc), also my body gets trembling, heartbeat speed is increased in that hostile situations. facing difficulty to find words in both situations, "stuck during the talk and afraid in hostile situations" When any person asks me any question suddenly. I'm unable to get the response quickly. Sometimes I get the wrong answer Mostly when I was going to do any work suddenly I forget that what I was going to do I'm afraid of firecracker's sounds (or other sounds like this) but not any effect that same sounds on other people who are near me. A lot of things rewind in mind.
