Do I need help?

A lot has happened in my life lately, a lot of bad things. I feel so alone and unhappy and I think it’s starting to affect my parenting. I take care of my son but feel like I’m not there... if that makes sense. Like everything is happening and I’m just there and my life is passing me by and I’m not as present and happy as I should pretend to be for my son (he’s 1 1/2 yrs old). I know he doesn’t understand why I get frustrated or randomly cry and I don’t know what to do. I feel completely alone. Should I look into counseling? I don’t want to be on meds but feel like maybe this isn’t normal and I could potentially benefit from something to make me happier. Should counseling by itself be enough? I know everyone is different but if anyone has felt this way before, how did you get help?
