Hi there. I understand your frustration. Are you taking an anti-depressant? If not, you might want to ask your doctor which one you can safely take along with your other meds.
I have MS and cannot drive anymore. My vision has deteriorated so much I just don't feel comfortable or safe driving. So, that limits my out-of-the-house activities. Sometimes I get that jealous feeling towards people who have a job that's counting on them to be there. It's good to feel like you're needed in life.
It's been four years since I've worked outside the home. It's hard to find things to fill all the hours of the day. Especially things that stimulate your mind. I read alot. I've had to switch to large print books but they make it easy to read again (with reading glasses

) and enjoyable.
I wish I could volunteer somewhere. I love being around people and helping. Nothing helps you feel better more than helping someone else to feel better.
I know what it's like to have to live on a budget. Disability doesn't come close to what I was used to making. I'd been at my job for close to 16 years.
Sorry I don't have any quick fixes for you.....just wanted you to know that I understand the way you're feeling.
