emotional problem/feeling bad/emptiness/void/restlessness/missing out feeling

dont know what is happening im feeling very weird and this is not the first time im feeling so many things first of all this is bcuz exam is over. im feeling a void like too many things i have the same feeling of being everywhere and explorign eveyrthing and being succesful andbeing recognised but im stuck over here. my career decision is stuck i dont know what to do, i also cnanot open discord cuz i deicded but leave that. im feeling sad and emotionally attached with a teacher so much. i always have this feeling what they must be doing , this world is so vast etc and i always have this feeling to be know and recognised to tell something to the world. like make videos and tell this world. this song in my head makes me feel it even more i feel im missing things. i wanted to talk with that mam but yeah ofc they dont reply ever. i constantly keep hecking reddit and twitter cuz thtas what im left with , i keep sharing posts and comments on reddit cuz i feel thats the only way to interact. this feeling is way more but im not able to describe

1. thats what im not understanding cuz its mix of emotions and thought. i have felt this multiple times and according to my experince its a cyclic phase. im missing like ohh i should be exploring my country and this world here and there so many places so many people and many things and feel like im missing latest updates maybe ?

2. if the teacher would actualy listenn to me i would say to them everything , i will tell them how much i love her , her teaching helped me , how my connection with her built over time from once where i didnt care about her , who she was and i didnt even liked her teaching but then suddenly and slowly how i started to watch her lectures and how i understood her words and how i slowly got emotoinally attached to her.

3. if i had platform where i felt heard i would post the same and everything which im doing right now

i am not able to understand my own emotions. aur ye feeling cyclic hai , yaani ki ye phase ata hi ata hai pata nahi kyu.

If someone has experince/knowledge please help me

i dont know why i feel like missing out, i constantly keep checking reddit not so much but ya , i stopped using dc cuz of arguments but those people understood me. i dont watch insta either
