I gained... does that mean I failed?

So I gained 0.2lb this week at my official weigh in (at the WW meeting). I was prepared for this, and honestly I thought it would have been more like 1.2 lbs. A part of me is relieved it wasn't more, but a bigger part of me is feeling a sense of failure. I joined WW to lose, not gain. I cannot afford to go to meeting for years and years in order to lose the rest of this weight... so a week with a gain makes me question how long this will really take. I am not looking for dramatic weight loss, but even a small amount lost each week would make me feel as though I was reaching my goal. I feel like I am at the point right now where in the past I would have jumped off the bandwagon and eaten the chocolate bars and cake.
Speaking of cake... there is a full one sitting in the fridge right now. I am not allowed to look at it because it is a suprise for tomorrow (my b-day), but I do know that it has 450 calories for 1/10th of the cake. YIKES!!!!!!!!!!!! Plus, my bf is making me dinner tomorrow so who knows what to expect! I am pretty sure it will be homemade turkey lasangna considering he bought all the ingredients for that today... hopefully he makes it healthy!
So my goal for this week is to be at 146 by next weigh in, drink my water requirements, and follow my workout schedule... is that too many goals?! Hope everyone is doing ok!
