Go out with your husband for a vacation. Take some rest. Your health is of the utmost priority. All our lives we put 100% emphasis on material gain and money. But we don’t concentrate on the thing for which we are earning i.e. us. Go and arrange a picnic. Spend your time with your family. And pray to God (Christian prayer if you are christaian) Or Salat if you are Muslim. Even if you are christian your intentions should be as if you are talking with God.
If something is bothering you and you are not telling it to your family, just blurt it out. Keep your heart and mind light.
Give some of the old clothes to the poor so that you feel contended that you have done something for the humanity.
Use bright colors in your home, bright surroundings. try to take time to watch extremely comedy movies, read comedy books etc. And when its beyond limits, cry out and take out your sorrows through tears.
Think about those more un fortunate than you. I hope these things will lessen your depression.
Very few Pakistanis have the concept of depression.
Ultimately , it is you and your own will who is going to save you. Believe me, I have also been a depressed person but I tackled it.
