I understand how you feel. But life will look brighter if you manage it a little bit. When you get up every morning, tell yourself "I will have a nice day and will not let anything disrupt that". At the end of the day, always think about one thing that was good. Only work on having a nice day TODAY. Yesterday is already gone; tomorrow can wait. Try to be in a good mood, for your child, but most importantly for yourself. Life is so short. Make the best of it. Life will get better.
