Hey it's okay it seems hard at first, but when you focus and try to understand things, it will all get easier.
Don't worry just try to concentrate. Believe in your self. Be brave that's is nothing that a human can't achieve . I know sometimes we need people to hear our problems but when we don't have people there is only 1 alternative take a book and put all your thoughts on the paper u'll find relief make a habit of writing diary when u feel like saying things to some one write it on the diary and the loneliness will disappear and u don't need someone to hear ur problems . and All the best for your future
Don’t worry, you will be able to manage things efficiently, try to make a schedule for studying and pick one thing at a time.
