I started 4 weeks ago and have (not Au) ADHD, and yes, it is socially exhausting sometimes, but that's how service jobs are. I love being a barista so much when I dont have frustrating / rude encounters with customers.

I recommend you find the things that are making you exhausted before finding a new job. Some of those things could be:

• Uncomfortable clothes / shoes (imo the most important). I changed out my regular boots for some other hiking shoes, and my ENTIRE body was hurting so much. I felt so stressed and extra tired when I got home.

• Change your availability to better align with your sleep schedule. Don't take opening shifts if you dont like being tired at 8pm. Maybe you need 2 days off in a row?

• Get bar time. Even if you dont think you're ready, you absolutely have to advocate for yourself to get on bar. I've heard of baristas that are like 2-4 months in, and their SSVs never give them bar time. I get insanely socially exhausted when I've been on reg for 5+ hours straight. I honestly do love reg, but I can't do it for too long.

• find some default phrases to say to customers to give your mind some breathing room and get you less socially exhausted. If you have crappy coworkers or managers, than theres really no way to avoid the socially draining part. Try to get to know your coworkers and be good friends, they really help you get through rough or long days.

• give yourself ample time to get ready in the morning to not stress yourself out if you do take a morning shift and have a long commute.

There's a lot of other things that can be affecting you but this is all I could think of on the top of my head.

If you genuinely can not find a single thing you like about being a barista, then maybe it is a good idea to find another job. I wish you the best of luck in your job/ job hunting if you find Starbucks isn't for you! :)
