head hurts, inside hurts

Im not so good.. not so bad. a little calm. but often feel light headed in the morning at around 1030 to 1130. light headed. and when im well in the day, coping well, dealing with her nonsenses and trying the my best not to let her affect me.. not to let people affect me, i would get a terrible headache by the end of the day. mostly occur in the evening. i would feel like im not in my body, light headed, alternating between tired and trembling, heart racing slightly. hand shaking. and yes, nauseous. this has been happening frequently in the last 2 weeks. is my body trying to tell me something? i try to control my attitude . but it's so tiring to fight all these. im tired. yet everyday i have to motivate myself to get of bed sometimes i wish it will end. wish that i don't have to be accountable to so many people. very sad.
