When it comes to depression I really recommend a therapist or counseling because it depends what category or like level of depression you are in to really determine how to cope with it
But avoiding isolation could be good to try to have someone to support you
Do things to keep you distracted and motivated
(depends on age and your access to things but going out could help ofc always be safe because of the pandemic)
exercising or meditating are also other things and joirnaling also helps some people but it really depends how you are and the type of depression you are in
