Suicidal ?

Sometimes I️ get an overwhelming feeling that dying and not living or thinking at all , would be easier than living and thinking and stressing ...but idk why. Is this being suicidal ? I️ don’t know ,I️ don’t feel like I️ want to die all the time but sometimes I️ get those thoughts and I️ dont know why I️ would feel that way . I have gone through bad depression for a whole year (2015-2016) pretty much lethargic but I️ don’t feel that depressed right now. Both my parent have anxiety and depression but ive never known them to be suicidal.
