Philosophy: When do i stop feeling bad

In this post i want to ask some questions to everyone:

If i was walking and and saw a beggar and put some money in his cup and then saw another and also put money in his cup and so and so on when do i stop putting money in their cups when does it become socially acceptable to stop giving in charity when does it become morally acceptable
when i myself become poor when i feel self-satisfied or when i feel like a better as a human for putting 2 pence in the hand of a shivering poor person who has no home and lives of liquor and coffee
when do i.

Should a person change the way they act to be 'palatable' for other people should a person change the way they walk and talk should they shorten their name so that they can be seen as an equal is that Okay to make yourself different so that other people like you.

Please comment your answers for both these questions.
