I think im depressed?

ok so im 16 years old and 11 months ago we moved out of state and i left all my friends and family that i grew up with behind. (its just me, my mom, and her husband here) and everyday i miss my friends and family more. and it just gets to the point where i've thought about suicide. i made friends here but i dont really care about them i just hangout with them so im not bored. and my moms always trying to force me to get me to do things with her even though i cant stand to talk to her. i was gonna get a job and buy an airplane ticket back to my home town and stay with my sister for the summer so i could visit friends. but my mom wont let me and i would need her to drive me to the airport. my mom wont let me cuz shes fighting with my sister. and i feel depressed all the time. please help
