Can I pursue Aerospace Science after Class 11?

Help me!!! 1.I'm starting new "work" on my own(challenging for me) but my mind says quit it, be quite & do nothing. I myself don't know that wether the result of work will be +ive or uncompleted like alws. 2. My mind has become like order seeker type, when someone orders me, I do those things with dedicated(but sad from inside) manner. But when myself will try something different(which i fear, but necessary) then. "I QUITS IT" & sometimes I don't even start. 3. I'm like stuck no clue what/whom I want to do in life, I'm in cllg(1 yr) doing (CSE) ,. 4. I want to do/try (sports,talking girls,study,stocks,coding..) many things, but myself, my thoughts(overthinker), R like just be in the place where u are[confused,po*n,think about past/future(being billio..re,olympics..), girl (that u liked & never talked), abusive/beating self,.. sometimes feels like end life, but don't hv courage for that also.. 5. I tried self help books, spirituality, god, self affirmation, writing... & thay affected me(sometimes) but for only some time, then again that devil me comes up &these things never get completed. As no one in my family knows about all these, so that's Y ,I hv to fight/loose/try again, the battles with myself.
