I’ve battled clinical depression all my life. That said, you can go take a pill and talk to a Dr. until you are blue in the face and it may not help you. Depression is just anger turned inwards. Here is what will help you regardless of the situation that is causing your issues:
Exercise at least 20 minutes a day
Eat better food
Stand up for yourself.
Make a list of all the stressful things in your life. All of them, don’t leave any off. Then number them by most stressful and eliminate the worst one.
Quit filling sorry for yourself.
Come up with a plan to get out of debt and take 1 possitive step towards that plan immediatly (rebudget, sell something, etc.)
*filling = feeling. Sorry about that.
The point is the same, though. Quit letting yourself be a doormat. If you stand up for yourself to your ex then you’ll feel 1000x better.
Good list.
I’d add: Go to Church. Get involved in a Prayer Group or some other volunteer activity. You will find that there are folks in much worse siruations than yours. Reach out to help others and your good deeds will come back to you.
