Glioblastoma diagnosis

My husband has recently been diagnosed with an in operable and incurable glioblastoma brain tumor. Since his diagnosis his depression has gotten worse, I am caring for him on my own. We have no family in Ireland they are all back in the UK. I'm struggling to get the support I need my own health as decided to fail me with tonsillitis and laryngitis. He doesn't see me as some one looking out for his best interests he's had a number of incontinence issues of the last few days and gets very aggressive when i try to clean him i have no home help or carers sorted at this point they told me that they have people on there books who have been waiting since November. when I broke down and asked what am I supposed to do, there reply was 'i don't know'. I desperately need help I feel like I'm sinking. I just need someone to talk to. My husband was diagnosed on the 21st of December. But since the summer he's been segregating us from our friends. I have no one to turn to and no one to talk to. I know this may seem selfish of me thinking of my own needs and wants but I'm still only human and I do everything I can for him. Why can't I get the help I need for me. Please be honest and tell me if I'm being selfish. I understand this is hard for him I really do. I watch my caring, kind loving husband disappear and a man I don't know take his place. I know it's hard for him to come to terms with this as well. I'm only 27 and the last year has gone from great to out right cruel. I'm not sure how to handle this. I feel like I'm losing my own identity. Sarah.
