I'm new as well, and I understand the doom and gloom outlook. Remember-you are SO NOT ALONE! There are so mnay people out there with depression, and while we are fortunate to have found help, and this support forum, there are people out there who haven't found help.
Look at things the way I do-your husband loves you, and will support you through this bump in the road. You have 3 children, who no doubt adore you, and that's what makes you special and worth everything!
Give the medication a chance to work-I just started Lexapro on Tuesday, and while I'm a little tired, and feel kind of strange-I know that means they are working to make me well. I am looking forward to that light that I can see at the end of the tunnel. I would like to hear your progress, as it is important to let us know how you are-now that you're here, we care.
