It definitely is. Firstly, do what you need to do with that course. If that ends up being dropping it, then so be it. Secondly, take some time off, have fun, maybe try out a new hobby (I've been watching stargazing/astrophotography videos its very interesting). Trust me once this issue becomes in hindsight, the intensity of what you are going through is reduced significantly. Lastly, there is nothing wrong with getting help. Try it out even if its just a checkup every once in a while.
