Uncomfortable - Life

Has anyone been at a point in their life where they feel uncomfortable with everything? Uncomfortable with their job, uncomfortable with their home, their environment, etc. I’m currently at that point in mines, where I feel like I need a major change. I just don’t know what it is. Im uncomfortable at my job, I uncomfortable where I live currently, I’m uncomfortable with my lifestyle, my mental state, my body. I want to completely start over or just do something different with my life. Unfortunately I’m such a reserved person that I’m not one to be brave and open and venture. I do also have a family.
