I don't have anything to look forward to are the weekends.
Why do you think you don't have anything else to look forward to?
Because I have no other interests.
While it may seem difficult now, it is good that you correctly identified that the cause of your problem is because you do not have any other interests. You should work on improving yourself and getting more hobbies and interests so that you can have more things to look forward to in life. It might be hard to get started but the payoff to your mental health will be worthwhile and considerable.
If I only there were things I can get excited about on the weekends, I want to die.
I am so sorry you are feeling this way. I think you may have depression and therapy and drugs can help you through this.
