Lockdown triggered panic attacks in me, severe panic attacks with fear of collapsing, having a seizure, dying, that would last hours. 
This has been going on since the first lockdown.
What's happened is that when I am with someone, I am fine. Weirdly I can even manage to get out and about by myself, go to the office, the shops, whatever really.
My problem is I cant be alone since this started happening. If my partner is out and I'm alone in the house it triggers it all over again.
I suspect this started because during the first lockdown he was furloughed so we were spending 24/7 together. The panic attacks started once the first lockdown ended and we were "released".
Has anyone experienced this? Panic at being left alone? I feel fucking ridiculous and dont know how to get over it.
