Am I a bad friend ?

So my best friend wants to borrow 1000$ until she get paid. She got evicted from her house so she applied for a new place to stay 3 weeks ago. She got approved 3 weeks ago. She have been going out, buying weed, calling off work. Than on top of that her boyfriend pretty much stay with her. And he knew she had to move 3 wells ago as well. Now I feel bad because if I don’t give her the money her and her son will be homeless for awhile. & I don’t mind helping my friends but it’s like she don’t do instacart to try to make money, she spend money on weed & she been going out almost every weekend. Meanwhile I stay home & save all my money and not go out. I’m just not sure what I should do and I must found out I’m pregnant so I know I can’t really lose 1000$
