Maybe someone can offer help or advice. (F/28, SW: 160, CW: 145, GW: ~120)

I am 25 pounds from my goal weight (though I am more concerned with how I look and how clothes fit) and I keep going through the same debilitating cycle. I know that changes don't happen over night but I often will have maybe three great days in a row. I eat clean, I workout. But then I can't even see the slightest difference (I know intellectually that it doesn't happen that way) and the mental block and discouraged feeling and I end up taking two steps back. Bingeing on stuff I don't normally eat, ordering and eating an entire small pizza…. 

It's been this way since I started. I lost the first 15 relatively easily (I had literally been eating pizza almost every night for three months -- I was extremely depressed and just could not get out of it) so when I cut that shit out, the beginning was easy. And now I've just stalled because, like I said, I take two small steps forward and one giant step back.

I had originally hoped to be fit by the summer. Now we're two weeks out and I still look and feel disgusting. Another summer of being miserable in my own skin.

How do you get over these mental blocks? It is beginning to affect all aspects of my life. I isolate myself, I don't go out anymore because I don't like the way any of my clothes look and none of my warm weather clothes even fit. I go to work in yoga pants and giant t-shirts because nothing else fits (fortunately, I work with my mother in her home office but it's still pretty shitty).

I guess just need help figuring out how to stay motivated and not lose hope. Because truly, right now, I feel hopeless.
<bot>: I get discouraged when I don't see immediate results even though I understand weight loss doesn't work that way. How do I stop?
