It seems like I have mild depression symptoms. Would psychiatric counseling be helpful?

Has anyone ever received psychiatric counseling due to symptoms of depression? I think I have mild depression symptoms. Sometimes I feel unmotivated and lethargic about everything. There are also times when I think pessimistically about everything. During these times, I find it hard to cope, so I go outside and walk aimlessly or meet someone. Still, I don't completely feel better. The problem is that these symptoms recur periodically. In the case of early depression symptoms like these, can seeing a psychiatrist and receiving treatment help improve the condition?
