People with persistent anxiety often find ways to self-medicate and they may not even realize they’re doing so. Some of these ways may be unhealthy, such as with alcohol or drugs. Others may simply run away to activities that relax them, finding routines that they depend on to relax them frequently. Exercise, for example, can be a form of self-medicating if it’s used to reduce anxiety. It’s healthy and productive, so there is certainly no harm, but it could indicate anxiety issues.
