As salamu alaikum. Allah says:

2:185 Ramadhan is the (month) in which was sent down the Qur'an, as a guide to mankind, also clear (Signs) for guidance and judgment (Between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting, but if any one is ill, or on a journey, the prescribed period (Should be made up) by days later. Allah intends every facility for you; He does not want to put to difficulties. (He wants you) to complete the prescribed period, and to glorify Him in that He has guided you; and perchance ye shall be grateful.

Sister/brother, we all get hungry when we're fasting.  Don't worry you're not alone.  But fasting is ibadat (worship), so you can take comfort in knowing that you're being rewarded for it.  Remember, Allah tal'la has made our religion easy for us and has not placed on us a burden harder than we can bear.  Allah Says:

2:286 On no soul doth Allah Place a burden greater than it can bear. It gets every good that it earns, and it suffers every ill that it earns.........."

I'm not sure if you're eating suhoor.  But I find that when I eat a lot I tend to be hungrier during the day.  It's usually best to eat less for suhoor.   I get the feeling perhaps this is your first Ramadan.  If so, try to keep your phisical activities at a minimum until you've gotten used to fasting (i.e no sports, walking long distance etc).  May Allah bless you for your efforts.  And don't worry sister/brother fasting will get easier for you in sha allah.    Here's a useful dua (prayer)  for you:

2:286".....(Pray:) "Our Lord! Condemn us not if we forget or fall into error; our Lord! Lay not on us a burden Like that which Thou didst lay on those before us; Our Lord! Lay not on us a burden greater than we have strength to bear. Blot out our sins, and grant us forgiveness. Have mercy on us. Thou art our Protector; Help us against those who stand against faith."
