Am i going crazy!

Just a few minutes ago i realized that i lost my debit card. I used an atm machine at the bank and i just realized that i didn't get my card back. I hope no one has stolen it. Then i was touching the back of my hair and a small chunk of hair came out. I have been feeling sick today, nauseous, and i have been feeling a little light-headed for at least a couple of weeks now. I need to go to the doctor. I feel like something might be wrong with me. I feel like i am on the verge of a emotional breakdown. I want to go home.
