My kids are my life. Giving them a good future is my focus now. But i was forgetting that for that even i hv to be happy.
I noticed that in your previous post about your children, which startled me a little, I'm glad you have seen the light, because your kids are your kids, and it is very hard.
I also know another indian woman who probably as it much harder than you because she is a local with 2 kids, with a very bad alcoholic of a husband, so do not believe you are alone.
You appear to be very level headed and although feeling down and depressed, which is a natural feeling under the circumstance, you must consider how long ago did all this happen, because the longer you spend in a depressive state, the worse it is going to be to get out of it.
My suggestion is remain focussed on your children and their future, they only have you now, and need you to be strong, there is no harm in getting out in the day and meeting new friends, you do not have to tell anyone at all.
Your private life is your private life, so just be yourself, guilt free, you need to move on, take it slowly and learn to live with yourself emotionally without falling for the next would be husband, you don't need that in your life at this stage. You are a free woman! Try to seek others in the same situation there are many, however always be cautious and learn to stand on your own feet.
I have no idea how old you are or your children, but look at the new you, that you may have wanted to become, have faith in yourself, and take up a little exercise which is hard i know, but worth it, because it stimulates useful hormones, which will make you feel more positive towards life in general, it takes time, but if you can push yourself off the sofa, and walk fast every day for 30 minutes, you are well on the way to beating a heavy depression.
