I’m so tired of constantly jumping from one project to another. I feel dead and exhausted by the end of the week.

We have multiple different portals/services/APIs, and lately I've been assigned to several different tasks for different projects at the same time. I find that it's very hard for me to constantly switch contexts, several times a day. What makes it worse is that some projects use different languages as well. I've been completely dead lately after finishing my workday. Anyone else ever had a similar issue? Maybe I'm just getting old… I don't know. I'm so tired of this 😦
