New and Excited!

Hello All! My name is Emily. I'm 24 year old wife of a firefighter/paramedic and a mommy of 3. Chase, is 4 and starting preschool this fall. Ava, will be 3 in May and is my little princess. Colten, is 2.5 months old. I had him in November of last year.
Growing up I have always been the skinny girl. I'm 4'11" and my weight then was 105lbs. When I had my first son I started off at 116lbs (my highest ever at that time). I gained 30lbs with him and was miserable. It took me 5 months to get rid of the weight and an additional 4 months to tone up. I got to my lowest ever at 103lbs. When he was 11 months I got pregnant with our daughter. I gained 29lbs with her and had the weight off in 5 months and toned an additional 2 months later. I became a runner after her and started doing races a long with my husband.
But in January of 2010 my husband got laid off and then broke his ankle/leg in 4 different places 2 weeks later. He was told no weight on it for 3 months and then another 3 months of therapy. We couldn't get unemployment that whole time. I went into a depression mode. I gained 7lbs in two months. Then on March 7th we found out I was pregnant again. The same day I lost my grandfather (whom I was close to) suddenly with no explaination. He was only 65. My husband didn't get a job and start working until June. All in all, with that pregnancy I gained 40lbs. For my frame this is a lot. Colten, was only 7lbs 2oz at a week late. So it was all mostly on me. When I had him I weighed 150lbs and today I currently weigh 123 with a lot of flab.
I know some are gagging at this, but please keep in mind I'm only 4'11" with a small frame. Doctors say a healthy weight for me is 105lbs. So that's my goal.
My calories a day are 1200. Which surprisingly has been fairly easy to stick to. I'm also doing an intense workout program that is 6 days a week. I'm looking for encouraging friends and to gain/share knowledge with people that have the same goal :-)

P.S. Hubby got called back to the station and is currently running 20 miles a week :-) Things 100% better
