Lately I've been feeling anxious about the end of days, death and the future in general. It started as a small worry but is now starting to take over my life. I'm worried because whenever I feel this way I feel really dizzy and untouched with reality. I've been told that I shouldn't feel this way because I am currently at a very young age. I have a feelin if this carries on it may affect my sleep schedule which it already technically has. Any help?
