bisjo but again, I know that from the start, I am going into this with my eyes very wide open.
I really have done my research, over a year of it, in terms of the best method of getting pregnant and finding a clinic and selecting a route. I have had to deal with snooty receptionists, with being told what I should do with my body, with being on one occasion, lied to about cost - none of that has been easy
I have saved, and saved, and saved some more. I have taken on promotions at work (partly for me, admittedly, but also to generate enough income to allow me to comfortably support myself and a DC.) I have in those promotions taken on difficult and challenging roles. I have had to deal with awkward, non-compliant and rude colleagues and some extremely delicate situations, alone.
On a more personal level, I have moved house, alone, many times, bought and sold property, again alone, four times to date. I have dealt with the car breaking down in the middle of nowhere, with no signal on my mobile phone (bloody Welsh mountains!
) alone. I have travelled alone. I have organised funerals (sadly) alone. I have been in hospital and dealt with serious illness including one painful operation, alone.
Why? Because I have a schizoid personality type and enjoyed it? Hardly! Because there was no other choice! I didn't enjoy it but then I didn't dislike it either, in the same way that one doesn't enjoy breathing, you just DO it! 
I'm not sure if I should be reading between the lines for some sort of "don't do it, you will hate it" or whether you're just sharing your experiences but I think a lot of new mothers, those in a relationship and those who are not, find it hard. It WILL be hard but as I say, that just doesn't strike me as a reason not to do it when the alternative is not to have a child at all.
