You need to keep trying different medications until they find the one that works for you. Always keep in mind that most of us are struggling finacially right now , so you're not alone there. You are dealing with a lot right now, and depression can easily set in. But you have to push yourself to do things, I know it's hard because I have to do it every day. I lost my son 10 years ago and went into a deep depression, then 11 months ago ago his son. I know when I just don't want to do something, or feel I don't have the energy, it's all the more reason to do things. You have to fight back in any small way you can until the proper medication is found, and so that you keep moving forward. You can't worry about them running out of options for you, there are new drugs coming out all the time, and you need to take one day at a time, because this is actually all we are promised and have. Don't waste your day worrying about things that may never happen, or that you can't change.
There are some antidepressants that are more stimulating than others. Maybe this is what you need. Are you in counseling right now? I think that would be a huge help considering everything your going through. Take care. Remar
