Struggling without proper roadmap and "guidance "

Hello everyone I'm Vaishnavi being a 2nd year computer science student it feels so confusing to start with things ..
1.When I do start learning things it feels so complex that I start learning something and end up somewhere researching about it .
2.Every time I do something I put effort to learn I would stuck up with what to learn ,how to learn, how to master it . Everything feels so confusing
3.I feel I lack proper guidance..so I would request any of them to please help me with it
