Well, we all have times in feeling despressed and down, even when we are married. Sometimes I feel I want to be single again, not to go out and meet other men. So don't think being married is the answer, because it isn't. I wanted to go into a ministry full time, but due to me being married, I can't, unless my husband comes with me that is, but he isn't as committed as I am.
Firstly I don't know your age and the reason for you feeling this way, but if you would like to me PM me with some personal background, then I will be there to help.
Here is something in the meantime.
Depression
Depression can be relieved by patiently meditating on God's Word and expecting Him to act. It's in the Bible, Psalm 42:6, TLB. "Yet I am standing here depressed and gloomy, but I will meditate upon Your kindness to this lovely land where the Jordan River flows and where Mount Hermon and Mount Mizar stand."
Prayer is a key to handling depression. It's in the Bible, I Samuel 1:10, NIV. "In bitterness of soul Hannah wept much and prayed to the Lord."
It is useful to count your blessings. It's in the Bible, Psalm 107:8-9, TLB. "Oh, that these men would praise the Lord for His loving kindness, and for all of His wonderful deeds! For He satisfies the thirsty soul and fills the hungry soul with good."
Praise can chase away depression. It's in the Bible, Psalm 34:1-3, TLB. "I will praise the Lord no matter what happens, I will constantly speak of His glories and grace. I will boast of all His kindness to me. Let all who are discouraged take heart. Let us praise the Lord together, and exalt His name."
Christian music can help dispel depression. It's in the Bible, Psalm 33:1-3, TLB. "Let all the joys of the godly well up in praise to the Lord, for it is right to praise Him. Play joyous melodies of praise upon the lyre and on the harp. Compose new songs of praise to Him, accompanied skillfully on the harp; sing joyfully."
Feeling depressed and discouraged doesn't last forever. It's in the Bible, Psalm 30:5, TLB. "Weeping may go on all night, but in the morning there is joy."
