Can anyone let me know why actually Tunisha killed herself?

i got to know her after her death , and found her so mature actor in her past show which i just watched on youtube , total 155 episodes , its called "Internet Wala Love" and she was just 16 and played that role so maturely ,,,,,she had a bright future for films too.... it all happened due to relationship with the male actor he played with her emotions okay but she should have moved on rather then ending her life....she got a new fan in me after her passing away from "Internet Wala Love" such a talented actress she was

Tunisha and Sheezan were apparently dating each other but allegedly broke up once Tunisha found out that he was having an affair. As per police Sheezan was avoiding her after break up and as per a witness they had a fight on 19 December. I think she had a panic attack few days before this too. On 24 December they had a 10 minute long conversation after which she ended her life
