I am 28 F from a country in Africa. I work for a company in Germany for an easy job (not related to my studies)
In 2025 i had a breakdown that had me think that i was useless and dumb, i was kind of lost with ly life. So i challenged myself that if i could succeed a PhD i could prove myself that i am not useless and not dumb. So i enrolled and my idea of research interested my university and i got an admission.
When my boss heard it, he wanted to know more about my phd insight. So i told him. He is willing to help me and even told me that he could see if i could integrate his research group in Germany and in parallel continue my work for them in Germany. Which is such a great opportunity.
I am really motivated. However, i don’t feel confident as much.
I don’t feel like i am an excellent person, neither a very intelligent one. And i am afraid in case i disappoint them.
Now, the PhD becomes a great matter. I gotta ask some questions
If master thesis is a beginning from doing a research, what’s the real difference of making a master thesis and a phD?
In mu first year, what should i prioritize doing? What can i alreadyy start to do and on which purpose?
If I am in STEM, how can i survive with this AI fast progress and do i contribute to a technological progress and avoid having an idea that already existed ?
Do i really have to be smart to have a PhD?
Thank you guys

So obviously, my mistake was that i was so jealous, possessive to someone who was not even my boyfriend.
However, i want to work on it to avoid that for my future relationship.
If you were already like that before, how did you work on it?
What would a psychologist recommend to do ?
And for people who never were jealous, what kind of mindset do you carry to fight it and what arz your boundaries ?
Thank you

There‘s a guy i have been obssessed for months (ee never met but everything was virtual) and seemed interested to me. We flirted for a long time before he ghosted me for 2 months and then we connected again. However i decided to cut him off because i also discovered a flirty chat that he had with a girl some years ago and i told him that i saw it. He was so insistive that he wanted to connect with me but that he had no liability to give to me because we were nothing yet.
So i really cut him off. A month later he contacted me that he really wanted to connect again and not only being friends but more than that as he still plans to meet me for real.
And i discovered that he actually still was in contact with that same girl. So i wanted to ask a little bit of transparency about the situation and what he really wanted to do and that i would have liked to stop what we did if it was not clear to me
However, he did not answer and it’s been some months now of me not having a bit of clarity.
Was my question normal, or i should have not? I think the silence he gave me could also a way to manipulate me into a state of mind where i should think that i did everything wrong and it really worked.
