I love my mom but she stays in the bed unless she goes to the store. Sometimes she does not feel like going to the store and she asks my stepdad and he freaking refuses which makes me mad. The only time he takes her somewhere is to the doctor which is good but he was told she should not be driving and he never freaking listens. I am so tired of seeing her like this. I do talk to her but she falls asleep when I do. Sometimes she drives me crazy and puts stress on me which makes me get angry and then my stepdad has to get on my case I don't know what to do.
That being said, if it is depression -- I 100% agree with the others who have opined that you need to get out and live your best life right now. You can't have her recovery for her, she needs to want it. And her husband should really be the one helping her through it. I wish you all the best and peace in your heart that it is ok to move out and move on.
However, in answer to your question of what you can do? Unfortunately, until your mom decides she is tired of living this way and wants help, there's not much you can make her do. But what you CAN do is live your own life. As hard as it may be to acknowledge, you are allowing your mother's depression to drag you down as well; you say your mom is only 67 years old; she could easily live another 20 years. Are you willing to allow her health problems to drag you down for that long?
You might *try* and have a conversation with her and suggest she get a complete physical; if you can come along into the doctor's office with her and discuss her not getting out of bed, then her doctor might be able to talk her into some sort of medication/therapy to combat the depression. But you can't force her to go, and you really, really need to start focusing on your life, your health and your future. That might mean taking a big step back from all of this, including (if you're still living with her) moving out to your own place.
I know it sounds harsh; You have my sympathy that you have to go through this.
