So sorry to hear that, Agma. i can very much relate to it. I have many job frustrations, which are mainly related to my line manager, but don't want to leave everything (friends, acquaintances etc) behind me at the moment. Trying to make it better at work is difficult though.
As to the pregnancy thing, I can totally feel your sadness and frustration. I'm much older than you and without a partner so for me it's something I really need to abandon the hope of but haven't been able to so far.
I know it might be not much comfort, but you can at least still get more IVF treatment and then were in a position to bring the child up with someone. Don't give up on it! You are too young for that and want a child too much!

Many hugs,
