Feel free to moan away, that is exactly what the forum is for. You are not alone in feeling angry that it took so long to get diagnosed as we have all experienced this.
I am sorry to hear just how bad it got and I do think your doctor could have been more sympathetic. Unfortunately, most doctors do not know or understand about SA and they do not know about the new clinics that are opening up around the country. It is also not a "trendy" condition so it is not seen as a priority by many health trusts.
If you want to get involved in raising awareness of the problem, then why not join the Scottish Association for Sleep Apnoea (SASA) www.scottishsleepapnoea.co.uk
and/or The Sleep Apnoea Trust (SATA) www.sleepmatters.org
These organisations are self help groups who help to raise awareness of the problems of SA. You may also want to check out www.osaonline.com
as this has good information on the condition.
As for the guilt, although again this is a common response, you really do have nothing to feel guilty about. Why should you feel guilty about having a serious medical condition that the doctors would not treat seriously?
Try to think positively in that you will now have even more energy, which will allow you to enjoy even more quality time with junior.
Hope this helps
