One thing I have found that consistently lifts my mood is, after I take my shower, taking some unscented lotion, adding 5-10 drops of Essential Oils to it, mixing it up, and spreading it across my chest. I particularly like Rosemary, Basil, Lime, Orange, Grapefruit, and Lemongrass. Putting them in an aromalamp always seems like a waste, since you have to use so much to get any effect, but this way you have that smell for at least a few hours.
There is no reason not to seek comfort in small things. You may smell funny, but unless it’s going to cost you your job, fuck it.
