Want my clothes to fit again and feel healthy!

I am 41 with 2 grown boys and a wonderful better half that encourages and supports me in whatever I do. He is my rock and I hope that with losing weight will encourage him to jump on the weight-loss wagon as well. I have been a Licensed Practical Nurse for 12 years and know this weight is UNHEALTHY! I am currently studying Health Information Technology and with the studies I find my self eating much, much more. I have gone overboard on the eating thing and really need to lose the weight. I'm tired of feeling fatigued all the time and having all the discomforts of being over-weight.

I want to lose 45lbs before summer, and I feel this is a realistic goal. I want to feel good in my clothes and wear a summer clothing without feeling embarrassed or uncomfortable. I want to feel energized!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! All I do now is HIDE.
