Feel weak

Help me pls....I feel guilty, regretted, worried, tired, fear and sad? eh...I'm so scared & extremely worry about EVERYTHING until I cannot sleep well for the whole 4 days, in the middle of the night I keep getting up..anddddd I don't dare to share this with my friends and parents. Aku rasa bersalah arah orang atu...aduiiihhhh stupid me!!!!! Inda berpikir bah awal-awal, tarus2 lagi tu ku menuduh orang atu...ku takut ia buat something arah ku!!! arrrghhhh.. ='(

I don't know how to ask for help to get better. How can I stop feeling terrible all the time?
