I had a c.s with DS, after failed induction and failure to progress. this was mostly due to spending my whole labour immobile on a bed and out of it on diamorphine and an epidural.
i found the recovery more psycologically difficult and it triggered years of awful PND
DD was a straighforward VBAC , with a brilliant recovery, no PND and i found it to be a really positive life changing experience
but i know lots of people have the opposite experience
one thing that sticks out to me that i would investigate further is this issue of a small pelvis... if it is a pelvis that is really to small to allow a baby to come through then a c.s is the best option.
if the small pelvis comment was never followed up or checked out then i would not focus on it too much
a lot also depends on why you had the c.s.. if it was a failed induction for example, and /or a malpositioned baby, which in conjunction with a smaller pelvis is not a great thing for VB
i would get to grips with why your first birth ended in c,s and see if it is something likely to recur
whether you go for VBAC or c.s you could consider a doula to help keep you calm and grounded or look into hypnobirthing
