having insomnia

it's already 5.50 am n im stil awake n still sitting infront of my laptop n do blogging... at tis time most people wud b awake n start their new day after having their good rest n sleep. why can't i do d same thing like others, or at least b like a normal people which they got right schedule 2 sleep or they can just sleep whenever they feel they wanted to. im being just like a nocturnal cuz not be able 2 sleep at nite. not every nite but mostly.. sometimes it's hard 4 me 2 sleep although my body feels very tired n exhausted. im having insomnia which is a symptom tat characterized by persistant difficulty falling asleep. among d things tat cause insomnia r such as caffein, stress, n depression. i admit tat im addicted 2 caffein bt i still control d amount tat i took. some says tat i need 2 drink milk at nite, switch off all d lights or try 2 put some lavender in my room. bt how far it can help me 2 sleep cuz i still can't fall asleep easily. when u look at my eyes, u'll know why i look like a panda with my ugly eye backs...
