i feel tired

I feel really old recently, i don't know why ,may be because i grew fat.
Recently, i wanted a camera so badly but now not that much, I bought some lotions and feel a little guilty.
so i stopped buying things recently, i even send back the camera i bought.
today, i calculate the loan i have to pay and want to start eveything a new next month.
i really need to re arrange my finance.
