Giddiness at gym. More complications?

I'm on telmisartan 40 mg for hypertension 140/85 and also Sertraline 50mg treated for general anxiety disorder. I usually get giddiness due to anxiety now and then and I have done my counselling on how to manage it. I'm also on a healthy diet and exercise regularly at gym. I had no issues working out until last week when I added more weight to my chest exercise and I felt very giddy. My blood pressure was 160/90 which is something I expected due to workout and anxiety. I'm worried if I have to avoid heavy weight increase, will feeling giddiness had any more complications? My ctca test was normal, stress test normal. Calcium score zero. Thyroid is none. Kidney and liver test were normal. I am 6ft and 96 kg. I'm not fearing of gym if it can kill me by increasing my workout. I was well hydrate and breathing well during workout.
