Anxiety attacks

Hi ladies. Is anyone else suffering from anxiety attacks ? I've never suffered them before but if late I get so overwhelmed and panic. I feel like I can't do it all, in fact I can't even do much right now. They do come out the blue seemingly, my heart just races and I feel faint and can't catch my breath. I have an appointment with my doc in about 2 weeks time. Is there anything I can do in the meantime ? I just can't even talk to my husband about it, because he thinks I'm just picking a fight or being overly emotional due to hormones, but I'm really stressing about everything, from finances to how to parent a blended family and I'm also stressing coz I feel like as is I'm parenting my step son alone, I end up even stressing about folding the washing coz I've spent the whole day cleaning.
