Babydubs just to chip in on the mental health side of things...if you don't mind!
I don't have bipolar but complex PTSD resulting from a v traumatic childhood. Therefore I have similar fears about being touched, needing to feel in control etc.
With my DS I had a very long labour and EMCS. One thing I did was to put a note on my birth plan about how staff should comfort me if I had PTSD symptoms in labour and made sure all staff were aware of the diagnosis. I noted on my birth plan that I would only consent to internal exams if totally necessary due to my issues (as it happened, I had several, as they were important for my monitoring and I didn't mind them at the time). When I was helped to the shower after the op (about 8 hours after it), the nurse just stood outside the curtain and talked to me, she didn't come in with me! She helped me to walk to and from my bed.
Oddly, what I found most difficult was being touched a lot on my breasts as they tried to get my baby to suckle in the following 3-4 days in the hospital. Midwives had to manipulate my boobs and showed me how to hand express milk by squeezing my nipples etc. I wanted them to show me, because I wanted to breastfeed (I went on to breastfeed and enjoy it, mostly, until DS was nearly 2). But that and the constant intrusions of nurses coming in to check on you when you were drifting off to sleep or to monitor blood pressure etc actually got to me more than anything involved in the op.
I do recall the anaesthetist at some point during the op saying that they were about to insert a suppository in my back passage and I remember feeling a bit panicky but by the time I asked 'Why are you --' he said 'All done'.
One thing nobody's mentioned I think is that I had a weird, 'floaty' feeling every time I was drifting off to sleep for a good couple of weeks after the c-section, I think somehow it must have been related to the experience of anaesthetics.
I definitely couldn't have made a party or walk around the park the same week, but everyone heals differently, it's important not to put any pressure on yourself though - caring for the newborn at home may well be enough!
