not so new to MFP from westchester county

Hello everyone my name is Maria and Ive been on this weight loss roller coaster for some time now. I am at the biggest Ive ever been (bigger that I was 9 months pregnant with either of my girls) I need to lose 50lbs by May 24th as my step son will be graduating from Marine bootcamp and I want to look my best. I thought reducing my cal intake would be helpful but it only hurt me more so I was on 1200 cal & over doing the supplements and ended up in the ER. Im starting fresh again tomorrow starting P90X I just need help getting motivated to work out I have 2 small girls and a sick husband that takes up alot of my time so by the time I get a min for me to work out Im over it. Im hoping i can find some ppl to give me the push I need so I can get back to a healthy weight not just for myself but for my family as well. feel free to add me the more support the better.

Thanks
Maria
