depression makes it difficult to find an interest. Depression is caused by several things. Whatever started the depression the depression causes chemical changes in our brain. Being pregnant and giving birth also changes our body's chemical make up.
Physical ctivity such as walking at least 20-30 minutes each day help the body fight the biological causes of depression. Sometimes I have to force myself out of the house. If you have stairs in your house, walking up and down them might help. Then there are all the other ways of getting exercise that have been mentioned. I've found that if I have a goal I can get out to walk better. Frequently my goal is to buy one thing at the store. Bread, milk, a can of peaches or a non-food item, chap stick, a barrette.
If you're not sure about taking medication try the things that have been suggested here. Walking to the store may create a friendship. Even tho I live in Portland, I have casual quasi friendships with a couple of store clerks. And these are not the personality types that I would ordinarily choose as friends. For me it's fun to chat a few minutes with almost anyone.
Your baby is small enough to carry in a front pack. If you start now walking with him you won't notice his weight so much as he gets heavier because you will be building strength.
I've lived in the country where there were no sidewalks and walking next to the road wasn't comfortable. If that's the case for you perhaps you could drive to a place to walk.
It is really important to get good exercise not only for your mental health but also your physical health. If you get started young it won't be so difficult to keep it up as you get older. The voice of experience. :)
I've had depression difficulties all of my life. I'm 66. The first 15 years of treatment was psychotherapy only. I was missing work. With therapy I could make it to work even when I felt like crying. Then along came medication. The first medications made me groggy until I got used to it. Then came the SSRIs. They help a great deal.
I love to read. My 3 brothers don't read anything but the newspaper. If you like to read a good book can take you out of the doldrums. I live an exciting vicarious life.
If you don't have a library near you, you can order books from the State Library.
If you have a car, a short drive, might help. Doing anything to get out of the house usually helps alot unless the depression is serious.
Finding and trying things to do is one way of finding out how serious your depression is. If you find that hardly anything takes the sad or even detached feelings away it is time to ask a doctor about medication. Writing to Mama Source is a good sign. smile!
