Sorry to hear you are going through a hard time and having fired can be a traumatic experience, I have had that before and can still remember that phone call. You will get over it, I would say there are too many companies with great cultures out there so it's just a matter of time and effort when you find your next one, just think it of like numbers game. I would also suggest working on something you are passionate about and finding a community of like minded individuals, that may bring you joy :)
