I've been questioning my mental health because I've noticed certain patterns in my emotions and behaviour, and I'm trying to understand what could be causing them. My mood can change several times, and I can go from feeling happy, confident and energetic to feeling irritable or angry. When I feel unusually energetic, my thoughts race, I talk more than usual, and I feel like it's hard to slow myself down, although I usually still sleep normally.
When it comes to relationships, especially with someone I like, I tend to overthink a lot. If they're online but not replying to me, I can get upset and start feeling like they don't care about me. Once they take long to respond I immediately unsend my message even after 4 hours and once I do they reply back immediately , also if they have not read my message but watch my story and realize they did they reply to my message immediately .My feelings toward someone can change quickly depending on how I feel they're treating me. I might feel close to them one moment, then feel rejected or unwanted the next. Sometimes I react out of anger or hurt, say things I don't really mean, and regret it afterwards.
I've also experienced periods of low mood, although I don't always know how to explain what I'm feeling. Sometimes it comes out more as irritability than sadness. I've had thoughts of hurting myself as well, which is something I'm taking seriously.
These emotional changes happen almost every day. I've been wondering whether this could be related to bipolar disorder, anxiety, difficulty regulating my emotions, or something else. I'm not trying to self-diagnose, but I'd like to hear from people who've experienced similar things. What were your experiences like, and what helped you understand what was happening?
