Confused

So I haven’t been feeling like myself lately I’m the strong person for everybody around me and I try to keep their spirits lifted but the entire time mine are in the dumpster and feel like there is no getting them out like I’m happy person for them to make them feel good bc I can’t even make myself feel better or just comfortable in my own skin I come home and just sit by myself and sometimes I cry or I drink or I sleep and I feel like I’m sinking deeper and deeper into depression but I don’t show it around the people I love and care about
