Hi, my name's Danielle, im 18 and have gained 50 pounds in the past 3 years due to personal medications. I've been able to get off all of the medication but i just cant seem to shed the weight. i've been eating right, (most of the time) but as soon as i get ready to go to the gym i take a glympse at the mirror or head to the car that sudden burst or excitement diminishes and i go back inside and sleep

Can anyone help me with some tips or even some motivational words?
