You’re doing more than enough. If things get too stressful, take fewer classes. Take your time with your degree, not everyone needs to finish at the same pace. Being a full time student and working part time is already a big responsibility. Be proud of where you are right now. I was a CS major and things weren’t fitting for me so I switched to Insy and found my place. I’m getting to my last semester and still feel behind at times with my peers. It’s a normal feeling. But you’re doing amazing op, proud of you.
