Regarding beta blockers. The age of 32?

Hello Doctor, I'm experiencing high BP since last one month, mostly during evenings. I have consulted with two doctors, both has told me that it's happening due to anxiety. My ECG and echo, and all other reports are normal. One doctor has told me to take Bisotrak 5, and the second doctor has prescribed betacap 20 and told me to discontinue it after two months. As per my knowledge, these are beta blockers. Which medicine would be more effective for me ? If I start taking betacap and discontinue it after two months, will that give me bp spike ? If I can control anxiety by myself, do I really need to use beta blockers at the age of 32? I would really appreciate if someone can answer my questions. Please, I need help.
