I’m confused whether or not I just experienced a hypomanic state or not and would love some input. 

I don’t really like shopping. And am typically pretty lazy and buy online if I buy at all. My husband recently bought me a new pair of shorts and I loved them so I found myself at a store buying like 4 pair of these shorts in different colors and ended up walking out with a new swimsuit too. 
Anyways, I have a big event coming up that I need dress for so my mom and I decided to go shopping for some dresses.  I went with her and she said she was buying at a few stores so I picked out tons of clothes. I’m talking like $600 worth, which she paid for. I was having such a great time trying on clothes and loved so many of them. Then I got home and over the next 2-3 days I online shopped like crazy. I bought even more new clothes for myself. I ended up spending like 600 more dollars out of my own money (which I don’t have).  I also typically say no to credit cards when offered at stores but I opened up two just to get a discount on the clothes I bought and then I paid them off as soon as I got them in the mail. I bought a good amount of clothes for my daughter too. 
During this time I would say I had more of a restless sleep but I still slept. 
I was not overly energetic, nor did I talk to much or too fast. I was fairly calm…minus the increased heart rate and excitement/thrill I got when buying new clothes. To be fair, I haven’t bought new clothes for myself in years. I almost felt normal and not depressed with the exception of overspending/shopping. I really struggle with depression. It’s like I popped out of it for a few weeks. I did not feel euphoric or overly energized. Just happy. 
I had some pretty intense and out of character sex with my husband the other night too. We stayed up way too late and I was miserably exhausted afterwards. 

After about a week or two of shopping and spending money, and not the best sleep, I’m exhausted. I feel kind of crappy. And I have literally zero desire to shop or buy anything. My drive and motivation to do things and be social has trickled off. And I’m feeling pretty guilty for both mine and my moms purchases.  I just feel SOOO lazy again. But I also had like 3 nights of hardly any sleep because of sex, something that happened with my dog, and watching too much TV one night. 

I have ADHD and my psych is trying hard to figure out if I have Bipolar disorder or not.  When I tell him about things like this he just suggests that maybe I was having a good day. I don’t know. Does this sound like any of your hypomanic episodes?? When this happens it’s so short lived…either a day or a few days or a week or so. Sometimes I feel wired like I took an adderall or like I’ve drank way too much coffee for no reason but it only lasts a few hours. 

Any input would really help me to understand this better. 

Thanks so much!
