hello
no I don't have digestive problems either. Perhaps they are hormonally linked with you - how old are you, do you mind me asking? some people say you can get them during menopause and others notice they can get worse before their period or whatever. I have noticed no pattern to this myself. I have tracked everything.
If you think they are hormonally linked and you still have periods, what about taking the pill because this might level out your hormones a bit?????? A bit of an experimental idea there! I don't know if it's the hormones that would make your ectopics worse, or if it's hormones that make the anxiety worse. I think that my hormones make my state of mind a bit more loopy at certain times of the month.
The only thing I notice is that in certain situations or body positions they are worse. eg. when I went to a wedding recently they were terrible. I didn't know anyone there and I'm not very good at anything like that. Also if I bend over or get up quickly this can trigger a real bout.
I have come off ssri's before - I had no problem at all coming off them. But unfortunately after a few months off them the panic attacks and anxiety came back and the ectopics got a lots worse. so I have spent the last two weeks going on them - I found going on them worse but it's several weeks in and my anxiety is feeling improved. I am no longer avoiding going out. I am completely anti-medication really - things have to be really bad before I take anything because I don't like putting stuff in and messing around with myself. But honestly after the nightmare month of going on the tablets I can honestly say that it was worth it - my sleep is better than it was, and I don't feel weird 100% of the time - much less often, and sometimes I even forget about my ectopics, and other symptoms.
I wouldn't worry about low BP - most doctors would say it is a good thing. sometimes you can get it a bit if you aren't drinking enough - so make sure you are taking plenty of fluids - water, herbal tea, weak tea whatever takes your fancy but nothing dehydrating or that will make your palpitations worse

In fact low blood pressure is probably desirable because it means your arteries aren't all clogged up - think of it that way.
I think that kind of thing can be worse if you are tired too, and if you have a lot of anxiety then you probably do get quite exhausted - I know I do, so try to take a break if you ever can and slow down what you are doing.
Best of luck and hope some of this wibbling helps you with your thoughts
