Hi Julie,
Sorry to here you are in a bad place at the moment, I really do know what you are going through and so does everyone on this forum, who will give you loads of help, advice and support whenever you need it, it really is an excellent forum and will help you through the dark times. Facing up to your problems and taking the steps to get it sorted is the hardest part and you have already taken that first step. You really do need to sit down and tell your partner, don't face this alone. Your loved ones will handle it better than you think and will want to support you through this. If you have been facing it alone for a while I think that they will already have guessed by now that something is wrong, so being open about it will help them to help you and will also be a huge relief for you so you are not going through it alone. You will get through this, there will be a solution for you and there will be light at the end of the tunnel, may not seem it now and it will be an emotional rollercoaster, but you will get there, just hang on in and share it with your loved ones. Keep posting and you will get some amazing support from this forum, it has helped me so much. I don't know which company you will be talking to, and it's not for me to give advice on this, but I would strongly suggest speaking to Melanie direct. Melanie and her team are wonderful and will give you sound advice, I don't know what I would have done without them. Hope you get things moving soon.
All the best
Mike
