You could write about the effect lockdown has had on several individuals and groups. Lockdown has greatly obstructed people's ability to see and spend time with their loved ones (friends, family, romantic partners). This doesn't only apply under lockdown but also with restrictions on travelling overseas, as people may likely face insurmountable problems as they attempt to travel to meet their loved ones in a different country under current circumstances. You can also highlight the sudden change in lifestyle, from being able to go to your physical workplace, go to the park, go to a restaurant/pub, go to a sporting event etc. (i.e. being able to enjoy life when you can, implying a normal life), to having to stay at home most of the time, not being able to go to your physical workplace/educational institution, not being able to have a night out and not being able to support your favourite sports team etc., which is quite a detrimental/chaotic change, and explain the psychological effects this can have on people, particularly if lockdown remains enforced for an extended period of time.
