Hello, I was put on effexor about 1 and a half week ago and by the second day of using this medicine I was experiencing what I believe was mania. Symptoms included: Rapid speech, impulsive decisions(mostly wanting to make them and getting close to doing these impulsive decisions like buying expensive stuff just because I can and having unsafe sex), jumpiness, excessive happiness and energy. But the effect only lasted for a few hours which confused me beyond belief since 1. Anti depressants take full effect usually 2 weeks after the original intake 2. Mania/hypomania last for 4 days at least.  


Now with that in mind, I've been carefully noting down my mood pattern since my severe depressive episode and what my psychiatrist confirmed was accurate description of a manic episode.   


Since I did have a depressive episode lasting 4 months, I've had 2 other depressive episodes lasting 3-4 months too; meaning that I've had 3 depressive episodes (they got progressively worse each time) within the span of 2 and a half years and 1 manic episode meaning I fit the criteria for Bipolar disorder.  


I haven't had such episodes occur (the last manic episode and severe depressive episode I had was in 2020) but I've noticed a really unstable change in mood, not really noticeable but still it's there.  


I am really confused, was the anti depressant dose too low to trigger full blown mania? Am I too young to have bipolar symptoms appear? (I am in my late teenage years). Am I overreacting and overthinking this? Is it my anxiety simply acting up? I am so confused. I am going to start ADHD meds hopefully tomorrow, can these meds trigger mania and can I clear my suspicions then?
