Hi! Welcome. You mentioned you're sleeping all the time. Have you had any blood work done recently? It could be anemia, low B12, low TSH, or hormone imbalance.
Going to the doc is always best. If you can't afford a regular doc, are there any free clinics around that you could get checked out at? I know some women can get assistance for a well-woman exam through Planned Parenthood (they can also get you free birth control if your fatigue is due to a hormone imbalance -- that was my problem). If that still doesn't work, maybe you can find some information on-line about increasing iron or B-12 in your diet. I think it's pretty hard to overdose on iron if it's just in your food, but I know you have to be very careful with iron supplements plus they can sometimes cause stomach upset. Drinking more water can also give you more energy. I'm really bad about that & end up dehydrated a lot b/c I don't absorb salt like normal people so I have to drink extra water. Uggghhh! I hate drinking so much water, but it does give me more energy to face the day. :)
Karen had a great idea about trying to get a little exercise in. Other than that, is there something you can do to meet people? I know bars are out of the question when funds are low, but maybe you could try attending a religious function, joining a book club at the local library, getting involved in a neighborhood organization or local women's guild, or (my favorite) volunteering. There are lots of great ways to meet people & everyone is short on funds these days so it seems like people who wouldn't normally get involved in those kinds of things are now looking into them.
And of course, you can always come here to talk. :)
