Motivation needed

I can't begin to say everything that I have done wrong with my health in my life. However, I am tired of being overweight. I hate it...but apparently I don't hate it enough to stay on track. I was doing great... for like a month. Then I started back in school. Between two jobs and school I just lost it. I am so stressed from the house hunting and school and work. I absolutely hate my new job. I get peed and pooped on hit and kicked by Dementia patients. I understand they don't know anymore, that's why they are at our facility and not at home. However, when I was hired I was expecting a different job. We treat the residents well...and that's what has kept me there for 3 months. I am searching for a new job...but with everything else its on back burner...well I should say everything is on back burner...but hey.

Anyways, back to the real story. With all my stress I am not packing my snacks/lunch anymore. Which started out okay...I wasn't eating anything at work and was making a daily trip to the subway across the street for lunch....Then it turned not so good. I started eating the junk snacks we have for us and the residents...Ice Cream bars, donuts, cakes, brownies...ya you got it. Then I got extremely tired of subway(only 2 sandwiches I like(cold cut, and ham) I layer it up with lettuce, green peppers, and onion. Then a small amount of light mayo)) So I started going to Martins Deli and getting Chicken Tenders and Mojo's. I also stopped drinking as much water and started on diet pop(blame the bf on this one...he wouldn't let me keep a water purifier pitcher in his fridge and instead bought me diet pop) I also haven't went to the gym that I pay for in over a month...I signed up with the boyfriend under the impression he was going to go as well and well..when working 17 days straight with one day off this last month he hasn't been so cheery to go.

I know how to eat healthy...I know what I should be eating. I know that I shouldn't have bought the Krispy Kreme Donuts that I bought yesterday...but I did. My main issue is that I am incredibly picky. Picky to the point that my tastes rule out so much of the healthy food that I am stuck eating the same thing over and over again. Unfortuantly, my tastes like a lot of the fatty no no food. Although they are still pretty picky.

I have one motivation...at 190 pounds, my boyfriend will have to quit smoking. This helps...but its such a "long term" thing..that the little...oh ill have this one thing today wins out. Especially with the boyfriend being such a huge fast food-junk food addict. I can't not buy the stuff he likes...if I don't he does. So its always around. And we constantly have to go to McDonalds to satisfy his fix...so I eat.

I wan't to lose the weight and gain my life back. I started at 222 and am down to about 201(that was checked last week...probably up a few from being off track) I want to get to 160...and at 190 he will quit smoking.

Wow...this has turned into a story of my life. ANYWAYS(adhd girl needs to stay on topic) I am looking for help with motivation. How to do you resist the donuts in the break room, the cake for someones birthday(at my job its like twice a week). How do you say no to the Fast Food and go home and eat something else...How do you stay on track?

Also...If someone of a similar weight/height as me could direct me to there success story it would help. I am worried that its not going to help. I know the weight loss will...but I am worried that I will hit 160 and won't see much of a difference. I am almost at 20 pounds lost and I don't see or feel any changes. It is quite depressing. The boyfriend is always...oh I see it here...and I see it here...but I feel like he is just doing it to motivate me. Anyways I am 5 foot 7, started at 222 and am looking to be 160(doctor's recommendation)
