She left me today 💔

I was talking to a girl since last month after being divorced 1.5 yrs back We were completely into each other and very compatible But today the end was inevitable, her Toxic ex came back to emotionally back mailing her and she left me being stranded at the same point. Am very broken and shattered again the i was earlier after healing a bit. Not sure what to do and whom to talk with . Please help 😞
