Heres my Story?

Okay so im 16, I weigh just under 140, about 138, and im 5’3. Its not good enough and i despritley need to lose more weight. I recently got a workout room together including a treadmill, a ab lounge a tony little gazelle, a exercise ball and a rolling wheel. I need to look better and feel better about myself by june. That’s my goal, here’s the thing, how do i deal with wanting things that i no i cant have, is there anything really healthy that you think i’d like that i can eat instead of eating the bad things that i want. and how should i go about losing about 10-20 more pound by June? please help me. Thank you!!
