Many people think they are a "slow loser" but in fact they just have unrealistic expectations from shows like My 600 Lb Life, which features people who lose "fast" because they are much bigger than your average WLS patient. You may still be a slow loser; I can't tell how much of your 33 lb weight loss was before surgery, but I lost about 9 lbs on average per month for the first 6 months after surgery, and my surgery center said I was doing great!
Try to focus on things you can control, like eating and drinking and exercising the way your surgery center recommended, and don't worry about the scale. You might also focus on how your clothes fit or other "non-scale victories".
You might also consider reaching out to your surgery center to make sure you're on track, and consider seeing a bariatric therapist.
Good luck!
