Relatives asking for money

Morning. Happy Easter. My relatives have been in debt since god knows how long. I have lent them money with little in my account. Yes they have paid it back. I gave them some for a car repair because I felt guilty because another relative who has just got some inheritance gave them some money. They are asking to borrow again. I have lent them money. My other relative has been splashing out lately on a lot of things. About 6 years ago i opened an envelope from the bank which said i was nearly 2 grand in debt so i took my relatives who had power attonery on my account due to me being quite ill with my mental health,and i managed to get myself out of it by budgeting a lot. I asked what they did with that money that a relative gave them,they couldn't answer me properly. I still have problems with my mental health and it stresses me out when they ask for money. I lent some to the relative who now has some money and that has now been paid off. Why can't they ask the other relative and not me? I am out of work and my relative and spouse work. Please may I have some advice.

Thanks for the reply. I went to the bank with them and took them off my account about 6 years ago. I had to do it. I spoke to them earlier and said that next time they ask to borrow money,to ask the other relative. The amount I lent for a cheap second hand car has been paid back.The amount for the car repair a few years earlier has been paid back. And the amount for a tyre a few years ago has also been paid back. It was paid back with a payment plan. It just irks me that they still ask me even though the other relative has some inheritance now. I said I didn't get much money. They said they didn't either. Between them,they get more than me. They quickly changed the subject. I shall say no next time. Someone else can help for a change.
