Lexi,
I cannot over emphasize the dangers of experimenting with multiple psycho active chemicals that have not been fully tested. The worst case of a bad reaction is life force termination. Please stop doing this. Be more careful in what you put into your body.
To answer your original question, Estradiol will lower the aggressive nature of the usual male hormones. Many of us feel so good about this that we describe the feelings as mood elevating. Estradiol is not a mood altering drug. We have gender dysphoria and when we feel like we are in the proper hormone state, we feel so good that we describe our feelings as euphoric. What we feel is nowhere near the feeling anyone would get from any of the intoxicating chemicals, such as alcohol, MJ, or any of the other psycho active drugs. We just feel proper and we are at peace with the world. Once I experienced the Estradiol boost, I knew I could never be happy going back to being under the influence of Testosterone.
No need to offer a reward for feeling proper. Life in the proper body and mind is priceless.
