Im worried with winter coming and the days being shorter with less sunshine because my depression has gotten bad.

Stave off that fear with a plan and with goals in mind. You know what's coming and what the risks are - minimize them by already knowing what you'll do to shift those unpleasant feelings. Have a contact list, a social group, an outlet. Plan for winter time outdoor activities.

Don't sit back and wait for problems. Have a plan so they don't come knocking at your door. You can do this - you've survived every single year up to today.
