You know my situation love, if I can give you one piece of advice it would be not to check twitter. You know what I did and it messed me up big time, I don't know how I made it through the night - yes I do - MN. I came off FB and I'm not tempted to look anymore (did it twice). It also means I don't need to hear how wonderful other people's lives are.
Try, try not to torture yourself, I know how hard it is. You will not heal while you focus on him with yoga lady and what they may/may not be doing.
Those thoughts come in my head too, they nearly destroy you and for what? They are not hurting over this, you are. I am trying so hard to focus on my healing (even got a fringe cut today, never had one before but cheaper than botox). My problem now is disbelief at what he's done to me, not what he's doing with her.
I know I'm probably not in the best position to give advice as I am still healing but these thoughts of them are tearing you up. Please try not to do it to yourself.
I know the significance of this holiday for you and know that you will find the weekend hard with his birthday, my H birthday is next week so I understand, but why don't you treat yourself, have a massage, get a fringe cut, buy some clothes, even if online to stop you having panics at the shops.
You no doubt feel terrible when you shout at your DCs, try to make this holiday good memories for them, cuddle them lots. I always get strength from my DS. Take lots of photos and when you get home, go with them to buy some frames and put them in together, let them choose where they go in the house.
With the ADs, I didn't go on them for 3 weeks as I was so worried about the side effects. I have been on them for almost 8 weeks now, I didn't even notice side effects but they did take about 6 weeks to kick in. Not saying you won't get side effects but please get advice from your GP. Don't rule them out, start your healing process. I am also on beta blockers for anxiety. My panic attacks are still there but not every day now and they aren't as severe.
Please look after yourself x
