Is it the contraception or the baby

So I’ve got the copper coil in for about a year now and I feel anxious, worried, easily stressed as well as I easily sweat which is very unusual for me. I can’t figure out if this is the contraception or if its the fact that I’ve got 2 kids now. I feel like the symptoms are worse now that my husbands not here did he help me forget them?

Does anyone else experience this?
