Bless you,
I know exactly how you feel!! I am sitting in bed feeling exactly the same , out of control . I had a stressful time at the beginning of the year and what with the peri meno was feeling quite poorly. I had reactive anxiety then , but my PMT anxiety brought on by HRT is hormonal I think, if that makes sense? I don't know what's worse? It's hard to understand if you haven't experienced it.
I am for want of a better word 'terrified' like yourself, afraid of being worse if I do or don't do anything. Can you tell your husband that you feel like this and ask him to support you , so if you feel a bit dodgy he can be there and if the worse comes to the worse you can always escape outside for a bit or go home? Sometimes knowing that there is an escape route (even if you don't take it ) helps.
I am not an expert but I would ask a doctor before taking anything such as starflower oil, I shouldn't think it will override the hormones anyway , but maybe adding another thing at the moment to worry whether it has caused a reaction is not a good idea?
I understand the desperate feeling of wanting to feel better and hoping that something will work. It would be lovely to enjoy life and be happy, but it's an uphill struggle at the moment!! I do hope you manage ok this weekend , try to maintain a sense of humour if you can. Sometimes I can see the funny side, but not at the moment .
