I don't know

I'm not so sure why but there are some times that I just feel so done with life, like I just want to "go away" if you know what I mean. I honestly don't know why I feel this way but it kinda got worse after I had my son almost a year ago. I don't want anyone judging me please but I feel like there's something wrong in my head that just tells me that I shouldn't be here, like it just depresses me and I don't know what to do😓😕
