Feel I have no time in my relationship and I'm starting to resent my partner for this... is it normal?

So I'm starting to resent my partner a little... and it feels like I have no time to actually do anything anymore... wondered if anyone else has been through this situation and if its normal?

Back story, my partner worked full time at a school and couldn't handle the stress of working there anymore. My work doesn't start till 9am, but I get up at 7.30am in the morning to drop her to work, once my work finishes at 5.30 I'm then picking her up or something I'm picking her up earlier as she finishes earlier. She is now working Tuesday and Wednesday elsewhere and 3 days at the school, Monday after work she then goes to do another job which I drop her to and then pick her up from so I have no time till 8pm. Tuesday/Wednesday she goes to work at 3pm, so I drop her and pick her up at 6.30pm, we don't get back till 7.30pm, it's a struggle to cook within the hour and get to her on time. Thursday she does slimming world and like tonight, I finish at 5.30 went to cook food, she is then doing a call at the same time and asked me to wait until the call is done as she is recording an interview with questions for tomorrow class before going to slimming world. Tomorrow evening is similar... I got upset and she doesn't seem to understand why... I'm literally starving and tired from work myself, just want to relax and rest.

Am I out of line here? I'm struggling and feel burnt out... she is learning to drive but with me most of the evenings so she doesn't have to have me drive her around in the future but I'm struggling now. Any advice?
