Why is work so hard

I don’t take adhd meds because I don’t like how they overall make me feel, they do give me energy to do things but also makes my anxiety higher and my brain race. I’ve always found it so hard to do 5 day work weeks I get so burnt out by the end of it and just do nothing on the weekend. Any advice? Would adhd meds actually help? I have short acting Dexedrine which is really low mg like 5. I don’t want to take it everyday but is it actually helpful for work? Seriously need help I don’t want to get burnt out and call in to work I struggle way too much with 5 days of work, especially waking up
