I just wanted to have a rant!! If I don't then I'm likely to say something to my boss that I'll really regret!

I have been at my current job only 6 months. I previously worked for a competitor compnay for 2 years but was unhappy. I got "poached" by the compnay I work for now and they offered me a job with them! Although I was really keen, I knew I was going to have to be totally upfront with them about the IVf thing and told them at my interview what my intentions were, giving them the opportunity to back out of hiring me. They said that it wasn't a problem. I have also saved enough holidays this year for when I need days off, etc. (We're starting treatment in July).
I spoke to my boss earlier to tell him that I am going to the docs tomorrow to organise my referel to the clinic. He suddently said that "he wasn't happy with it" and that "he has invested in me!". He also said that "he hopes its not going to involve any time off work".
I'm so upset and mad!! I never hid anything from them at any point. If I'd have known it was going to be a problem, I'd have stayed at my old job!! They assured me at the time that it wasn't. Now I've got the stress of IVF AND the stress of my boss not being happy with me and moaning everytime I have to go to the clinic, etc.
I'm so mad!!




What do I do???
