That IUD contains a very small amount of hormone. I think that it is unlikely that the IUD is contributing to the mental issues you are having. Is it a continual mood swing or is it related to periods, assuming you still have them with the IUD. Not everyone does.

I'm not so sure social services is the best place to contact. That is were you go for financial issues and assistance with food and insurance. At least it is here I live. A suicide hotline or something along that line may be a better bet.

Do you have a regular therapist. If not social services may be able to direct you to a free, low cost, or sliding scale clinic. Just tell them you are looking for information on free or lost cost therapist.
