Not even sure if thread is alive anymore but, OP the problem with you isn't that you have emotions but you can't control them and therefore control you.
The major problem I'm seeing from this small post is that you aren't actively engaging your emotions and learning to control them. By letting your emotions control and dictate how you feel you revert to the past of sadness and self-pity. Emotions aren't bad, you just don't have the ability to respond to them.
>>>HOW DO I CONTROL MY EMOTIONS
I would say the first step to figure out what kind of person you want to be. Do you want to become a happy person? a grateful person? Determined?, etc. Once you figure that out than the real journey begins, but within a few months (depending on how hard the objective is) you should start seeing its effects. To give you an example start observing the person you want to be, most notably their habits and their mindset.
Everything is connected, poor dental hygiene is connected to poor heart, and so is your mind and action/body. For example if you wanted you want to be more of a grateful/happier person.
1. Observe the person you want to be
2. Start performing them (I.E Grateful people tend to reach out to people and say their thanks)
3. Avoid negative actions such as shitposting, and thinking or talking about negative energy. I'm not telling you to hate yourself when think these thoughts but be conscious of your thought patterns.
4. Finally I would say mimic the body language of the person you want to be. Negative people tend to have a body language and carry frowns, while positive people tend to have an open body language and smile more often. Start mimicking these patterns everyday for 5-15 min and eventually it'll become 2nd nature. If your interested in this kind of biochemical feedback there's tons of research on it.
5. Repeat for 1-4 for 4-6 months, if it doesn't work than ditch this plans and adopt another one. Just because this works for me does not mean this may work for you.
