Trying to Lose Weight

at 20 is weird. All i want to do is Eat Eat EAT!!!! When I'm bored I eat. When I'm sick I eat. I am so tired of carrying this extra baggage. After taking the Depo Shot for 2 years. Then having my IUD for almost 2. I've put on 80 lbs. I am now 195 lbs. And my goal before the end of the year is to get to 140 lbs. Please help me with ways I can get this weight off. I'm a picky eater. I don't eat veggies. Why I dont know. I work 6 days a week mainly at night at SUBWAY!!!!! NO vehicle to go to the gym nor the money to....I feel like its hopeless
