Don’t feel like myself

I don’t know what to feel and I might regret saying this or thinking this but I’m tired of being a mom or how else can I say it without sounding like a monster.......... I have 3 beautiful children which I adore but lately I don’t know I feel lost I’m a sahm and I’m tired I wish I had a day to myself my kids rule my life nothing is mine anymore. I don’t have something for just me. I’m going through a rough time with my 6 month old and I am tired he only wants me I take care of him day and night I get no breaks

My husband is helpful but I always do more, I haven’t slept good in an over a month I don’t know how I’m still alive I feel like I’m dying inside. My 6 month baby happened while being on birth control and I never enjoyed being pregnant bc I didn’t want to be he’s here and I couldn’t imagine my life without him but during hArd nights I find myself thinking this is why I don’t want more babies

I feel awful having those feelings I always thought I was a great mom but I often think I wasn’t cut out for this like I’m not a good mom anymore

My arms hurt from always carrying my baby I’m just tired! All day I do everything for my kids and Idk I do t k ow what to say

Am I crazy what is wrong with me ??? I’m 30 years old and I try to remember who I was before I had kids or who I was before I got married nd I lost myself my kids and husband is all I think of now and I love them so much they make me happy but I can’t help but think these thoughts sometimes
