Am I a bad friend for not lending my friend money?

I used to work at government and I have a friend there who I met and we still talk till this day I got fired from that job and the only friend I only talk to there is she up to this day. Now I work as admin assistant at hospital and I heard she doesn't have a job now. I only earn minimum wage and living paycheck to paycheck. She texted me this morning asking to borrow money because she need it for her mother and she asked how are you? I remember back then when I was still working at government I lent her money and she promised me to pay next month and when I was asking her to pay me back she will always say she doesn't have money despite saying she will pay me next month and it took me 2 years to get my money back because I forced her to pay me back. Now Im scared to borrow money from me because she's hard to pay the money back and I still didn't open her message on messenger but I saw it on my notification thats why I read it. Should I tell her I dont want to lend money to her because Im also broke so that it won't hurt her feelings? Am I bad friend for not lending her money?
