Dear Shirley,
You will surely be in my prayers tonight. I know that I am only 20, and probably haven't experienced half of what you've been through, but I offer you some of my advice.
I have a heart for those who suffer from depression, having already mourned the loss of three friends from suicide due to it. Firstly, I encourage you to pray-- for your daughter, for your husband, and anyone else who may be involved in your situation. Pray, pray, and then pray some more. Though it seems like, sometimes, nothing is happening when you pray, remember that YOU are a child of the God of the universe, and He most certainly cares for His children, listens to their prayers, and responds to them. Secondly, if your daughter is attempting suicide, get her help immediately if you have not done so already. Children are a blessing from God, but they can be hard to handle, no doubt. Even in your daughter's times of rebellion, show some degree of patience with her, and if anything, at least try to show her that you are attempting to see issues from her point of view. At the same time, you also need to assert your authority over her as a mother. It's a tricky balance, but remember that people are fragile. You are fragile, your daughter is fragile, and so is your husband. Find underlying causes of feelings of bitterness, anger, depression, loneliness, etc., and try to work toward resolving them, if possible. Finally, your husband. Now, I'm not married, neither am I fully informed of the situation between you and your husband. I can only say this: I met a woman who was having severe problems with her husband, and she said that he didn't love her anymore. This turned out to be false. Her husband loved her dearly, but the day to day struggles between them overshadowed it. If this is the situation you're in, don't say your husband doesn't love you. Those feelings are lies, and shouldn't be believed. If this is not the situation you are in, find some support from other family and friends, and work out your problems in a way suitable to your situation. Don't ever believe that you are alone. There are people out there who will hold you up.
Shirley, I hope this helped in some way, shape, or form. Some of the advice may be obvious, general advice, but sometimes, it's necessary to hear it from different people, even strangers. If anything, know that there are people praying for you, and God is watching over you and leading you every step of the way. Stay strong in faith, because surely there are brighter days to come. I pray peace over you and your family in hopes that everything will be resolved.
In Christ,
Revalon
