weight gain

I'm only 8 weeks and feel disgusting. About 5/6 years ago I lost 50lbs. I went from 200lbs to hovering safely around 155lb +/- 3lbs. Then I shot up to mid 160s, but was able to get back down to 155+/-for my wedding in April '16. I gained all that weight back after the wedding so my pre-pregnancy weight was 169. 
Now I'm already 176. I'm freaking out. I worked so hard to lose the weight and keep it off for so many years. Obviously I knew I'm going to gain throughout pregnancy but just seeing the numbers and feeling my clothes get tighter puts tears in my eyes (thanks, hormones). I've been pretty active (I've been lucky with little to no nausea - don't hate me) and trying to eat ok, but being hungry all the time over the holidays isn't helpful. 
Am I the only one who's gained a bunch already? I'm so disappointed with myself. I'm scared to get back up so close to where I came from so long ago and worked so hard to keep it off.
