Ketamine Beneficial for Anxiety? Help?

Hi, TLDR: 29 years. On 5 medications, pain in chest and have headache while running. Been 5 years. What to do? I'm 29 years old and I'm having terrible anxiety and have pains in chest. They erupt any time and having this for the past 5 years. Currently I'm taking: 1. Nexito 20 mg once in the morning 2. Betacap TR 40 once in the morning 3. Buspin 5 mg thrice a day 4. Olanzapine 1.25 mg in the night 5. Tryptomer 5 mg in the night Previously I was taking 10 tablets a day. So this is an improvement honestly. I'm doing breathing and running exercises. So the thing is whenever I go for running, during the run, I feel a sharp chest pain and lightheadedness due to which I have to stop. I went to see a cardiologist and he told me that I have nothing to worry about but I'm getting my TMT done this Saturday to rule it out. Should I go for Ketamine Infusion therapy? Can it help? And no CBT doesn't work. Please don't recommend it. I have also tried TMS and that too didn't work.
