I've had a rough year

Nothing exceptionally terrible has happened--unless you count the miscarriage--but I have felt generally off for the past year. I have had several major external stressors, but I think a lot of it comes down to just not feeling right in my own skin. I was depressed last fall after RB weaned and I went to counseling for a while, which helped. My hormones changed because I stopped nursing and I also had to change birth control pills, which made things so much worse that I just stopped taking them altogether. I got pregnant (on purpose--not because I quit the pills) in March and then miscarried at the end of May, and that has been another hormonal upheaval. In the process I have gained 15 pounds. That's a lot of pounds in a short time. My body has been in so many different shapes since October 2003--I got pregnant, and then had a baby, lost all the baby weight, breastfed, stopped breastfeeding, got pregnant, got not-pregnant, and generally ate too much because I have generally felt like crap for a year. And I look like hell. Or at least like some other person that I don't recognize as myself. My weight has plateued--I'm not gaining anymore--but I have not been able to stick to a change in eating habits and activity that would allow me to get back to my normal weight. I just feel bad.
