Struggling

I'm having a hard time lately and have been more withdrawn from my husband and kids I feel like I don't even want to be a mom or wife anymore. I have tried so many medications and counselling but nothing seems to be making anything better. I really feel like I'm a lost cause and that my husband and kids deserve so much more than I can give them. I don't know what I'm looking for I guess just reassurance that I'll make it out of this darkness. ..
