I feel like i might be close to a nervous breakdown?

but i;m not sure,i'm 56 yr.old female ,with a lot of stress and history of depression,anxiety ect. but i can handle that, i've learned to. but when it goes beyond my control, i should seek help and i;m not sure if i;m on my way there or not, maybe someone can tell me if it sounds as if i am? some symptoms include:feeling numb,slow,unaffected mentally, verge of tears, overwhelmed,can't seem to get anything done,not caring how i look when i go out,would wear pjs,or sleep in my clothes,need time,dont have any!
