Self employment health insurance deduction when I could have COBRA also?

I have COBRA from my past employment. But my COBRA rates are going to increase from 1st Apr 2020. Having said that I am running my own LLC(single member LLC). Paying COBRA health insurance is almost around $1600 per month. Can i get any tax deduction for 2019?

From 1st Apr 2020- my COBRA rates are going to increase. Moreover I cannot buy dental or vision insurance(only health insurance as I rejected it during the time of separation). Having said that can i go for health insurance on my own for my family? I am the employer and I am the employee. OR i cannot go for it as I will be having COBRA from my past employer for another 15 more months? Please let me know. I was referring to these links - link1,
