Hello Under,
Whatever is going on is not something that you can diagnose or treat yourself. You need to get some help. There is not shame in this at. Everyone of us gets to a point where we need some expert guidance, be it with our car, our body, our mind, or whatever. You are at the point where you need expert guidance.
Please do something about this! Go to your doctor. Go to a hospital. Get some treatment. Tell a competent professional what is going on and let him or her help you.
You are making a large assumption that what you are feeling now was "caused" by your meditative experience. I don't know that and neither do you, but this is your life you are talking about.
If you do not want to get help from a "western" doctor then post what area you live in and I am sure that people here can refer you to another type of expert.
Regardless, you were brought into this world for a reason. Don't give up on yourself yet!
