Sometimes I access the extremes of my emotions more than others I believe...does anyone relate or know what to think of it.

Today I went to target and bought some teeth whitening strips and had a deal where 25$ in beauty/health section got u a 5 dollar gift card. Ive worked retail and I use to work at target so I go and return the item to then re apply the new gift card I earned bringing it from 35 dollars to 30. There was a moment though where I thought the associates made a mistake upon looking at my account. Maybe I was tired or what but upon driving back to target I started screaming in anger feeling cheated( I wasn't what I saw in my bank out for the fund returned was technically what I paid the gift card complicates things.) I go to target again and they explain to me the technicality...I showed restrained and smiled through the frustration having worked customer service and once I got in my car it was like a flip of a switch.

Suddenly, I was excited to get home and use my strips. According to my current nurse practitioner Im mildly depressed. I notice one a short notice a little things makes me snap. Afterwork I might scream in my car, dull the pain with weed, go workout, but then suddenly once the situation is resolved I go to the other side of things of extreme happiness for a short second even laughing at myself.

*I believe most people would have maybe responded in with confusion and frustration maybe but not to point of screaming in their car for 5 mins but in the moment I felt like I had to. Maybe it was really about some else deep down....idk...but if I didn't id feel like repressing something...my therapist told me not to get caught up in the screaming fit because it can make things worse...sometimes i scream yell to my father about coworkers for an hr...he generally agree with me and laughs at the hysterics but at times I can't help it. Its like after masking all day I'm gonna blow a gasket if I don't*

Alot of the people on my moms side of the family are kinda considered "erratic" for a lack of better term. My father side is a little more level headed. Sometime I wonder if it's just personality where I have these dramatic shifts in mood within the day and almost overreact or if its culture or bipolar disorder causing me to have access to the depths of my emotions on a dime.( Ive learned to mask the emotions while on the clock at work or interacting with others but fall apart alone till something else distracts me)

Does anyone relate and has anyone gotten better with emotional regulation and letting shit roll off ur back. I got better at it a few months ago but this month...idk. Also is mild depression stability for some? cuz i'd like to be baseline
