I used to feel the same with my ex-husband and I feel much relieved after the divorce. Thankfully we don't have kids. You said you don't work. You could apply for disability till you found a job. Even I don't work coz apart from depression and anxiety I have short-term memory problems. But I m looking forward to start working again from next year when I hopefully get a little better.

Talking about the nice time spent with your daughter when she was a kid, like Emotionally Dead has said ........ "I know you talked about your daughter growing up, and it's true. She is. But she is only 10. You still have the rebellious teen years and scaring hopeful boyfriends away with a shotgun phase to look forward to. You still have her getting married to look forward to, and you having grandchildren. Your life is certainly not over, and you still have a lot to look forward to."

For exercise you can try walking. Even I can't exercise much coz I feel drained out but walking 3-4days a week may be helpful for a start. You can start with 15mins and gradually increase to 30-40mins over the next 5-6months. You will need to lose weight if you have diabetes and getting a bit thinner is going to make you happy about yourself too.

For diabetes please see an endocrinologist. Diabetes can be vicious. Please don't ignore it.

Do you see a psych doc?I think you may be experiencing depression and anxiety with irritability. I had the same problem and was getting lethargic and losing interest in everyday things yet aggressive at the same time. I used to punch and hit inanimate objects too. My psychdoc prescribed me a small dose of a mood stabiliser(lamotrigine-but it can cause bad life-threatening rashes in some) along with a low dose of an anti-psychotic(amisulphride) and an anti-anxiety med(buspirone) and these helped a lot with the irritability. But the depression is still there and I hope to convince my psychdoc to give me an anti-depressant to pull me up. He is slightly reluctant to prescribe me one coz I have bipolar and it may cause me to relapse to mania. I have had two manic episodes in the past.

Hope these suggestions help and make you feel better. Hugs to you.
