Hey there! First of all, don't beat yourself up over it. It's okay. Weight plateau's are common. Nothing is wrong 
Secondly, if you're the calorie counting type, I would increase calorie intake by increments and do your best to hit that number for 2-week increments. If you aren't seeing numbers go up every two weeks, increase your intake.
Lastly, I would strongly suggest adding key fattening foods to your regular diet. Try consuming a cup or two of heavy cream each day (you can mix it with something else like fruit juice, a smoothie, or cook with it and make alfredo, etc.). Add into your regular diet an excess of butter, nuts/nut butters, avocado, and various carbs have been a godsend personally.
Hope your gain goes well!
