Weight gain trouble!

At my 22 weeks appointment I had gained 15 pounds total since I got pregnant. I am really struggling with this. I am not eating everything in sight, I am eating way more fruit than I ever did before being pregnant. Today I got on the scale and I have gained more! I'm 24 weeks now and I'm stressing! I have been drinking lots of water! According to my at home scale I have gained 17 pounds total. Anyone have advice or stories that would help? I'm about to fall into depression! I KNOW I am big so please don't make me feel worse about it.
