"So disappointed in the St Georges"

So disappointed in the way St George's has handled my situation.. I've suffered with mental health problems sine I was 14 & have been on antidepressants since then I've recently had my 3rd baby (7weeks ago) and I can honestly say it took so much courage on my part to seek help I stopped seeing anyone regarding this quite some years ago but as I felt myself dramatically reclining built up the courage to seek help but St George's has literally ignored me I've phoned at least twice daily for over two weeks with the promise that id be called back within the next hour (no phone call ever came) I live alone with my 3kids first just turned 2, second just turned 1, 3rd 7weeks.. I have struggled so much the last month with no help or support! I really feel that St George's & the staff I've spoken too have really let me down & have lost my trust & also made me believe I can't feel any better than this! I used to attend this hospital at the age 16 to 18 then moved.. Am now 27 and Was refered back via my midwife & was really at a bad point to allow it but now just feel plain stupid for confining in people that obviously don't care! I have no one to talk to plus literally no help with my babies.. They let me down when I needed/need help the most!!!!!
