Lonely

Not quite stir crazy, just bored and lonely. I don't start out patient physical therapy until the 17th--that will be 3 weeks without supervision of exercise program. It's something of a struggle to do that daily. I am going on walks at least.
It's hot--really hot. I don't want to stress myself, especially with the new med that puts me at higher risk for dehydration and heat exhaustion. I never did do well in heat.
Part of my problem here is that I didn't take my Celexa last night. I've taken tonight's so I'll be okay tomorrow, at least as far at taht part of the problem is concerned.
I'm sleeping a lot, and that concerns me--it always does. Am I falling into depression? Should I be doing something different? Is this a problem? Am I too passive?
And my phantom limbs seem very activated tonight.
