Fi you are NOT crazy! This is probably your way of grieving for your little plus you seem to have more on your plate at the moment with exams too. So try to stress less (easier said than done I know). I know what you mean about pregnant women everywhere (try to look at them as success stories and if they can have a baby then we and all those TTC can too!!).

As hard as it can be I find to help me I try to think about the positives:

1. We did fall pregnant which is a start
2. Most people that MC go on to have H&H pregnancies
3. Maybe something was terbbily wrong with our little and they have now gone somewhere safe
4. As I mentioned in point 2 most people go on to have many healthy babies!

In regards to your DF he is most likely grieving his own way which you may not be able to understand. My DH has tried to put the matter aside and tries to keep busy so he doesn't have to stop and think... me on the other hand, well I feel better having a good cry (which has happened quite often since we found out last Wednesday) I also find that it helps me to read some of the other threads where people post their good after their MC

Good luck... are you going to TTC soon?
