Can you go through life being sad

Can you go through life being sad? You manage life but never live life. You live life to be slightly comfortable but always second guess if you are doing the right thing. You always feel you should be grateful for what you have but you don’t feel right. You are not suicidal but your sad inside because you miss parts of you. You always feel that there are parts of life that you are failing at and that you are borderline depressed but you feel that even that is lazy and don’t want to fall into that pigeon hole. You always make the best of everything though you wonder if you should.
