In the past 2-3 weeks I have walked out of my job and gotten a new one, been unable to sleep throughout the night and run on about 3-4 hours of sleep that is broken into 1-2 hour shifts, made new social media, felt a lot more sexually aroused and have hooked up with strangers, spent about $350 I don't have on clothes and video games, and generally feel very productive until I look back on my work and I have very little done. It peaked about a week ago and I feel like I've been progressively levelling out over the past 2 days. This all started about 3 weeks ago when I began working midnight shifts on the weekend but school during the weekdays, so my sleeping schedule was screwed up. Then I had a very close call with a family member where I found them losing consciousness and had to call an ambulance for them. They are fine, but it was very intense and I've been afraid of finding them like that again. I am already borderline but my mood changes have always been for a few hours-days, never more than a week; and if they are longer mood changes they're always depression, never this feeling I have right now. Am I just working myself up or should I talk to my psychiatrist about this?
