How to cope with sleep disorders?

Hi, I'm 34 years old and since October Pandemic I have white nights. Staandard is 3 nights with open eyes, there are drugs, brainstorming in the head. I already use Relanium, Stilnox, triricco but it's just me oglupilo to this stopnoa with I have problems with concentration and assessment of the environment. For some time I have such tablets, which are called Na Sen. The only problem is that the treatment can last 20 days. I finished the treatment and again the same thing. I'm already falling out of bed and out of the house. The doctor says that these are the times and this is depression. How are you doing?
