### input:
I have 2 children and am 6 months pregnant. I have quite a happy relationship but all of a sudden i feel really insecure and i dont know why. Nothing in particular has happend but the last few days i have just felt quite down and emotional if i think about how insecure im feeling. I have sufferd from post natal depression before but this feels different and i dont know whats causing it. Also i feel quite sick with it which is odd and im sure its not to do with my pregnancy as ive only started feeling sick since feeling like this. Ive also had quite a long term problem where (i know this sounds so silly) but if my partner was to mention an ex or if i think i about him with anyone else, it makes me feel incredibly insecure and sick. I cant handle talking about his past life with any other women, and get very paranoid and feel like crying if i think hes looking at another woman. Hes never done anything to make me feel that way but i have always been like it and i dont know if all this is tied together. Its such a strange feeling and i wish it would go away. Please help me as its really getting me down. Thank you

Hallow Dear, The incidence in past is bothering your mind. You have very rightly said the need to talk to someone. Please seek for an assistance of a counselor. Of course, you should not right off other organic causes which may lead to such conditions, particularly with the history of postpartum depression. This condition is very commonly observed in anemic patients. Anemia increases the psychological instability. So please get your blood checked for anemia. Iron with proteins will help you in this condition. The other condition you should rule out is Thyroid dysfunction. Any type of Thyroid dysfunction is known to cause mood changes. Hypothyroid condition is more common during pregnancy. It may also affect the health of the baby and outcome of the delivery. Miscarriages due to hypothyroid state are quite common. So please get your Thyroid function test - T3, T4 and TSH - performed on your blood. Depending upon the results, you may need medication. Please do not ignore the problem; report to your Obstetrician, preferably with the blood reports I have advised you. I hope this helps you today.
