I am in a similar position at the moment, it's tough isn't it! I had a miscarriage last week and have had so many panic attacks since then... The advice I've had from friends /Dr /anxiety leaflets so far includes:
Pick a topic and go through alphabet slowly naming something with each letter, aka, animals could be Aardvark, Beaver, Cat etc and really concentrate on each item.
Call someone /talk
Journal every day or multiple times to get things off your chest before they get too big
Recognise it as a panic attack and focus on calm breathing /trying to think of other things than what is panicking you.
I have just picked up a prescription for some medication to help as well, as I don't want this to get worse / go on too long.
Personally I've been trying the above but mostly putting on an album tmof whatever music I know makes me feel good and distracting myself with something like candy crush /colouring in etc seemed to help a bit.
Here to chat and talk it through if it helps. Finding others who are going through similar is useful. Especially when everyone is going through shit, you have no idea who's coping with what and who has space available for you! I, like you, feel like I can't always talk to others about it as I feel they've got enough on their plates.
Hope this even helps a bit. Look after yourself.
