Anxiety is a very common symptom of adult ADHD, as the mind tends to replay worrisome events repeatedly.

An adult with ADHD may:
- move around frequently
- tap their hands or feet
- shift in their seat

A person with ADHD can get so engrossed in something that they can become unaware of anything else around them.
This kind of focus makes it easier to lose track of time and ignore those around you. This can lead to relationship misunderstandings.
This concern is similar to experiencing disorganization. Adults with ADHD often find it hard to effectively manage their time. They may:

While you might be open to doing everything at once, you also may feel unmotivated.
Coupled with procrastination and difficulty with organizational skills, lack of motivation can make it hard for an adult with ADHD to finish a project. They may find it hard to focus for long periods of time.
Although this may sound surprising given that restlessness is also a symptom, fatigue is a concern for many adults with ADHD.
There could be several reasons for this, including:
- sleep problems that can come with ADHD
