I'm not sure which category to put this in. One year ago my Dr. put me on Lexipro because of trying to deal with my new life change of moving in with my mom. (husband came too, but he's Never a problem ). Well on came the weight, I felt hopeless but well enough to eat and not care about it. I stopped the med in January and started to see a counselor. He really helped me to navigate through some issues and supported me on some future plans. Such as boundaries and asking siblings for a break. My mom can be sweet or a royal pain. I can't seem to get a better handle on the boundary issue. She has a separate 2 room addition. She just won't keep that darn door shut! And she is safe to be alone. She is constantly coming in to my house for bogus excuses just to see what I'm doing. She asked me yesterday if she was in jail because I keep the door shut. I find myself hiding on her with a bag of chips , cookies whatever is around. Then I feel even worse and blame her, then vow to not get sucked into her trap. But why do I keep putting my finger in the socket?? She is active at the senior center a few days a week, I drop her off and she takes the bus home. One day a week they even pick her up to go grocery shopping. It's like if she doesn't go out every single day she's in my face wanting to know what my plans are for the day. And I do take her out a few times a week, sometimes I just want to be alone.
Sounds like she's actually pretty busy. Make yourself busy too. Also, create in your home a little "haven" if you can, that you can retreat to and be alone. LOCK THE DOOR. PUT a sign on the door "Having some alone time"....and then do NOT open the door to her. Doing this has saved my sanity, as my hubby has a huge TV in our bedroom which I hate, and he refuses to move it or move it into the den, which is specifically FOR a TV. I gave up begging him to turn it off by 10:30 and if I fell asleep, he'd sneak it back on.
I gave up and moved into my own little corner of my home. I don't think my hubby notices or cares. I love the cool, quiet clean little room where I can have peace and quiet and not hear FOxNews raging on 24/7. I'd take an interfering mother over the sounds of FoxNews!!
You can take the hinges off the connecting door and install self closing ones. That way, the door will not stay open. Mother lives with brother and he did this to her, so the family didn't have to see/smell all the mess in her place. She was just like your mom at the beginning of her stay at brother's 20 years ago--but now she cannot even go up or down a step. Time will take care of a lot of the things that are bugging you.
As far as the anxiety (which is what I think you have, more than depression--a mild tranquilizer may help more than Lexapro, which sadly is known to cause weight gain.
Good luck with the boundaries, changes, etc. This is a hard thing to do. Bless you!!
