33 weeks Lonely and Depressed

I'm 33 weeks and I'm home due to the baby sitting on my sitactic nerve. I start physical therapy Monday. I know bed rest isnt ideal for nerve pain but due to the numbing I get in my legs when I drive for long periods my doctor thought it best I stay home. I've been working from home for 2 weeks now. Its driving me crazy already. I'm home all day alone, kids go to camp and hubby works. When they come home everyone is tired. I just dont know what to do bc this feeling of loneliness is getting the best of me. Recently joined two mommy and me FB groups so hoping that helps. Sorry if this post doesn't mke sense just venting I guess.
