Hey carlierae, Welcome to Healing Well forum. I am glad that you have felt comfortable to post here, this is a wonderful site to get support and information. A lot of us go through the same things as each other and can understand and sympathize greatly. I have depression and anxiety/panic, when my husband and I split up I went to my doctor and asked to be tested for all the STD's and HIV also as I had it in my head that he perhaps had cheated sometime during our 11 years together. I wasnt showing any signs of anything it was just the thought, but the testing wasnt that bad and everything came back negative for me which set my mind at ease. I cant really comment too much on the rash or medical parts you mention but we do have several members who are extremely knowledgeable in this in the HIV forum if you want to post in there, you are more than welcome. It isnt limited to people who have HIV. They could give you much better suggestions and advice then I could by far.
The thing that really struck me with your post is that it dosent seem that you take very good care of yourself. Especially if you are not eating. If you have been diagnosed with manic depression with can certainly interrupt all aspects of your life including the way you take care of yourself. You didnt mention if you are on medication for it or seeing a psychiatrist or therapist. If not then I would highly recommend it as you can not control that disorder on your own. I sounds as if you do have alot going on in your life and have many stressors that can contribute to making you physically and mentally ill. Since you have a child you have to look at taking care of yourself so you can take care of her in the best way possible.
We are always here so please do feel free to continue to post. Take care
