27 year old sister- Mom is an enabler

I don’t know where to post this.

I have a sister that is 27 yrs old she’s our youngest. She’s renting with her friends paying $1000 monthly. Actually my mom is paying $700 for that rent. My mom pays for her rent, her gas, she’s always ordering doordash using my mom’s bank, and my mom sends her money as well thru venmo. Now my sisters and I are getting really annoyed this is not the first time this happens it’s been happening for a very very long time. Since she was around 17 or 18. Everything is being paid for her. She started her own “business” before making necklaces and rings and that flopped because she claims she had depression. Before everything she was living with her first bf of 6 yrs for several yrs and then they broke up. She said her x doesn’t motivate her on going to school. But while with her ex she was already talking to this other guy. Stayed with him for maybe 2-3yrs then broke up with him again. Have another bf 3mos after and I can bet she’s already talking to this guy as well while being with her 2nd ex. And she also says that 2nd bf doesn’t motivate her to go to school to do anything just wants to play video games on his computer. Doesn’t take her out or doesn’t anything together. So they broke up after 3mos breaking up she met another guy. And this guy has a “good job” is a few yrs older than her. He’s making 100k a yr so for her he’s good to her. She gets motivated to go to school and do something for her life as well. But nope they broke up after a yr maybe. And it’s always about her depression her anxiety. She’s taking meds for it. My mom said she saw a dr before for it but I don’t think she’s going to her appts anymore. Just taking this meds thats all. We’ve always been supportive with the things she says to us. Like when she started a business where she makes necklaces and rings. But that flopped because she stops making them. Her depression started again and stopped making them. She said she’s going to school so many times. First she said she wants to do eyebrows and nails. And when done she will work with her friend who owns a salon so she just needs the license. my sister and I gave her money for that to get her license. Never finished it never went to school never went to work for her friend. It’s a cycle with her it’s tiring now both my sister and I are pregnant she’s due any day now. And I’m due in 2 mos. I don’t have the love and care anymore to help her I told my mom. I’m just done helping her even my sister is done too. But here my mom working doubles working at least in a week 80hrs and that double shifts. So from morning to 11pm or 10 she’s working. She’s fucking grinding just to help our sister. She doesn’t work right now she hasn’t been. And I forgot to mention she went to move to L.A with her 2nd ex before and my parents are the one paying for everything as well. Sometimes her doordash costs at least $200 a week. She’s a fucking freeloading bitch and I don’t even care to see her ever nor talk to her again. And that’s same way my sister feels about her we both blocked her as well haven’t talked to her for at least 4-5mos now after sending her a long msg. I just feel bad for my mom we told her to stop because she’s just enabling her and she knows that she will always get help from mom. She’s an embarrassment I swear. I needed to vent
