What you describe can be caused by doing too much meditation. Based on just your message I can't be sure how much meditation you are doing but you might try stopping for a while and see if you feel better.
What you describe sounds exactly like what is called "detachment". It is a state that is caused when the mind becomes very calm from meditation.
Also sometimes when you meditate and the mind becomes calm, tumultous thoughts of daily life decrease and you can become aware of other thoughts that might be lurking in the back of the mind that ordinarily are drowned out by the ordinary thoughts of daily life. This can result is a lot of emotions arising as a result of meditation.
Somepeople feel compelled to work through these emotions while others may prefer not to go that road. So if you don't like what is happening maybe you shouldn't meditate, or meditate less, or try a different type of meditation, or try relaxation exerciese instead of meditation.
