For every scenario there are three options. The option to accept and let go. The option to make a change. The option to leave. They are the only three.
Unhappiness occurs when you choose the wrong option or try to make a combination of options work. Unhappiness occurs when you avoid choosing. Friction builds until the decision is forced or made in frustration.
Putting up with something that you really should change. Staying when you should leave. Letting go when you know you should really make a change. Wishing something would change without making it happen. Jumping ship when you should have changed something or found a way to let go.
People let the same things bug them for years when they have options at their disposal.
Whatever is niggling you right now, there are three ways forward and the choice is yours.
