Does anyone wake up daily at 3am?

I have problems falling sleep. I haven’t able to have good night sleep as fatas I can remember. Went I finally fell sleep I have broken sleep pattern, and I wake up every night at 3am, I do not know why and I cannot fall sleep again, sometimes I go back to sleep at 6am. I do not feel refreshed in the morning. I have black circle under my eyes from the lack of sleep. Also feel irritated, sad, and brain fog/forgetful from lack of sleep. This is terrible. Any one have similar issues. Any suggestions or help would be appreciated.
