28 F - I don’t know what to do with my life

Been working at the same job for 4 years, I feel like a bad employee. I wanna work somewhere else but can’t leave yet due to a big project. Tried finding part time jobs online but it’s so hard to get picked. My savings are always the same amount because I don’t budget well. I feel like the people around me are richer and more mature. I feel so physically and mentally tired and stuck in life. Living with a mentally ill sibling who doesn’t deal with their problems doesn’t help either. I go to life coaching but I just feel like I dug myself into a hole I’ll never get out of. Same job. Same finances. Nothing new. What to do?
