Just relapsed after 3 years

I quit smoking for 3 years. But had a quarter of smoke 2 days ago and another quarter this morning.

Been having a tough time. I’m currently in Hong Kong because my grandpa was in the hospital due to having lung cancer. Two days ago he passed away. Before I left for Hong Kong me and my fiance had a huge fight and she’s moving out now too.

I don’t want to add smoking again to the pile. But now I’m starting to have nicotine headaches again.
