When we sleep at night we're not really thinking about anything. I'm not saying that this could not be anxiety because it could be. You also mentioned feeling thirsty. Is this a true thirst?
I always recommend seeing a Dr whenever anyone starts having unusual symptoms. Yes, this could be anxiety but something else could be going on physically.
thanks remar for your valuable suggestions.
but my main doubt is if it is a problem with vitamin then why should i not feel in the night while sleeping..i can sleep properly with out thinking about it.
only in the morning once i woke up and and start thinking about it and then the problem starts,
A burning feeling on your tongue could mean that you're low on B vitamins. Being low on the B vitamins can also cause anxiety. I know anxiety can cause so many strange symptoms but I'm really thinking this could be your problem. If you can see your Dr to tested for vitamin levels that would be great. In the mean time eat foods that are high in these vitamins. You can google foods that will let you know which ones are high in this vitamin.
