Over 40 and starting again

Hello all. Im a separated mom of 2 teenagers and in a long distance relationship. MFP worked great for me before and was at my lowest weight of 112 at 5ft 3 for 2 years. Slowly fell into bad habits and now back at 138 pounds and want to lose 20 pounds and get back being fit and active. Used to love the interaction and positivity of MFP plus know tracking works for me. Hope to get back to my former healthy self...one week at time!
