How can I boost my metabolism?

Okay so long story short I feel like I have damaged my metabolism. At first i was eating 1100-1200 calories and everything seemed fine. Now for the past two month I have lost my period, thinned my hair, always cold. And basically feel like crap. I was 150 pounds in October 2013 now weight 123.5 pounds. and guess what I'm frustrated because I have only lost 1 pound this month even thought I did everything right. I wanna get down to 115 pounds because I want to look good in clothes :/ (for all those that will say oh stop you dont need to lose weight bleh bleh) So I have decided to boost my calories to 1400 now :/ . Will i still be able to lose those last ten pounds and oh yea btw I workout using Jillian Michael DVDs
Ugh i feel like such a idiot and I want my body to be happy and healthy again :-) <3 oh btw im 18 years old and I'm 5 ft 6 inches and i wanna lose atleast a pound each week.
