Hi, I wanted to reply to this, as I too suffer from severe OCD and depression, always had the ocd but was mild until a few months before my dd was born(she is nw 8),(I knew I was having a girl a few monthsbefore she arrived), I thought I was going mad, literally, I had horrific thoughts regarding my baby and was so terrified to tell anyone, as I though they'd take my baby girl from me when she was born...but obviously it worsened when I had her, I didn't properly bond straight away and didn't feel tha rush of love when she was born, hate thinkng of that now, as I feel terrible about that, although I know now I was seriously ill, I finally admitted to my parents when she was 2 mnths old about the thoughts, and honestly believed my mum and dad would HATE me and take her from me, but they just started crying and hugged me, they had no idea how I had been feeling, my mum went straight on the phone to my GP and I was seen about an hour later, I was then referred to a psychiatrist, but at the time they said severe PND , but I knew it was OCD , said this to psychiatrist and he said MILD OCD, I was put on citalopram, worked up from 20mg to 60mg, my partner knew nothing about it(I felt I couldn't tell him),he left when my dd was 13 weeks old, and this made things much worse, I suffered these awful thoughts on and off for about 4 years.
In between this I had 2 miscarriages,to my current partner of 7 years(we have been together since my dd was a year old), then in 2007 I had my darling ds, who is now 2.9 years old, and when he was born I DID have tht sudden rush of love and for tht I felt guilty because I didn't have this with dd, but then I hadn't been ill through my pregnancy this time , we were just glad after 2 miscarriages that our baby was here, I felt great, despite an emergency c section, then 2 weeks after I had him....BANG!!!!!!! Was hit with those crippling thoughts again but this time a thousand times worse...I couldn't even hold him without thinking I was gonna do the most horrific things to him........it was awful,the gp put me on prozac which did nothing, then put me on citalopram again, my kids and me went to stay with my mum and dad for a week and basically my mum took over, I was very ill, at the May weekend my dad had to rush me to a and e as i was soo bad, they were gonna admit me to the psychiatric unit but no one was there over the holidays to do admissions, they sent me back home with my dad with diazepam, which helped for about 2 hours, and in that time I could bond with my ds, strangely I only had the thoughts bout my ds and not my dd, so I was referred to a psychologist, I had to force myself to go home in between ths and deal with the kids along with my dp, but he had to work, but I was so bad he had to take compassionate leave..
I saw the psychologist, who was a woman , and she was a godsend, within a fw minutes of being in the room she diagnosed severe ocd, and slight PND. After a few visits I saw things much more clearly and she was completely unshockable, I couldn't have gotten through without her....I still do get the thoughts from time to time, usually when I am stressed, but I now know how to just brush them off, but sadly since my son was 10 months old he was diagnosed with severe epilepsy, after the hospital finally did tests after us keeping on at them since ds was a few weeks old(he was having seizures then), and over time he has been diagnosed with a very rare genetic disorder affecting his chromosomes, he has brain damage(which is where the epilepsy comes in), he is severely delayed, can't sit up, or walk or talk and may never do these things, he has seizures daily, but despite ths my ocd hasn't been too bad , but I am still on citalopram and diazepam, but tht really is to help me deal with my ds's problems...pls tell yr sister to be strong, I am here if you need to talk anytime, I would also recommend the book "The Imp Of The Mind" , it helped me a lot, hope things are ok, and sorry about the long post xx
