Clinical depression is a serious condition. I of course haven't the expertise to advise the best plan of action however, there is a somewhat newer kind of psychology especially aimed at lay people who need a therapeutic plan of action.
Please check out on YouTube "Positive Psychology" this is a healing method specifically developed for folks like yourself. It is based on the human need of HAPPINESS ( sounds like an over simplification but rooted in basic psychological needs)
This psychology uses simple language anyone can easily grasp, it includes exercises that can put people suffering like you on the path to wellness.
Wishing you my very best.
