under home arrest

I feel like like I have been exiled in my own house.
I don't really go out unless it's for a doctor's appointment and when I do I feel like crap. My body doesn't seem to be able to handle the heat and the humidity very well. I get horrific headaches that made me feel like I can't function.
So I stay home and the more I stay home the less things I want to do. I spend most of the day yesterday lying in bed watching TV show re-runs and sleeping. All that is not making me feel good. I exercise and eat good but I am afraid I will get really depressed unless I find something to really entertain me while I am under home arrest.
I have a ton of things I can do and I should do but just don't seem to get around to doing them because I feel useless.
And the fact that I don't make any money bothers me- I feel guilty every time I spend money, even if it is just to buy food- I wish there was soemthing I could do from home and make money.
I 've decided I want to write children books but I can't seem to get around to do that either because I just feel so lousy.
May be I am already depressed.
I am so tired of the same old routine every day- get up, take a shower, have breakfast and wonder around the house for the rest of the day. It's just terrible- I need some change.
And the change is not going to just fall from the sky- i Will have to make the change but I don't know where to start.
I would like to cook more but it's kind of hard to cook up something just for yourself and Jeff is often not home for dinner.
I can feel the headache creeping up on me again.... aaggghhhhh......
