And when you feel that you are not the special one in their life, there are other people in their life whom they treat in the same way as they treat you, then just gather your dignity and walk away. As Jaun elia said:
بہت بھیڑ تھی اُنکے دِل میں
خود نا نکلتے تو نکالے جاتے
Tahajjud will affect you positively. It will change you positively. It will give you peace. What's better than talking to Allah in the middle of the night with a broken heart, When everyones asleep? Therapy is expensive, Try Tahajjud. Its free and it works.
