end of the line

I don't know what to do, say or how to feel anymore I suffer with anxiety and depression with paranoia normally it's controlled and I'm 'normal' but I can't take my meds when I'm pregnant (31 weeks now with a boy) my partner is so hot and cold with me I can't cope anymore I have been a nightmare I know I have but I would literally do anything to make him happy but he doesn't believe me and he has started to be awful towards me I have three older children two of which aren't his I just don't know if I see the point anymore I don't know how to deal with this I don't know if I am just being ridiculously sensitive or whether I can really be bothered trying anymore
