I always feel unstable and uncomfortable unable to manage my daily life everything seems like a tension to me and unable to stay calm and always lazy?

Talk to professional: Struggling to manage daily challenges, while feeling chronically tense and distressed, can make one feel tired and unmotivated. It appears that you are feeling overwhelmed with your current life situation. You would benefit from further evaluation by a mental health professional. Counseling can help you to identify underlying issues interfering with your quality of life. All the best to you.

See answer: See a mental health professional for an evaluation and treatment for feeling "unstable" and "lazy." You might specifically ask if you have ADHD (attention deficit hyperactivity disorder) predominantly inattentive. This diagnosis is often overlooked because children/teens who have it are well-behaved though chronically underachieving. Mood is often labile, which may seem like instability.

Overwhelmed.: It sounds like you may be generally overwhelmed with the direction your life has taken, which leads to both anxiety and depression. Counseling may help to redirect you and help you to develop coping skills so you can conquer those times in life that get to be a little bit too much.
