Always keep stock of water in an extra overhead tank or atleast an extra lid bucket bathrooms for emergency when tap water ran out. Just make sure to change water every two weeks to prevent bug parties in it.
If you don’t have kettle then have a lot of water bottles especially that can store warm drinking water for long time, to never run short of warm drinking water in winter.
Distract yourself into some offline activity which you love especially with someone you are comfortable with.
Once mind in place, deal with the problem which lead to depression in the first place. But if nothing can be done about the issue, then stop worrying about it. Work around it.
I make it look easy but I know its not.
