Ask HN: Tldr due to startup anxiety gf has left me, how do i get her back?

My manager at work has been pushing me to the limit and as a result have been carrying a lot of anxiety home leading to a big work induced difference with my gf. Also we have not had physical relationships in months due to this. Added to this my company raised a down round and i had to pay tax on my now worthless options She is extremely pissed and has left

What do i do ? how do i get her back?
