Mom guilt is so real

My son will be 8 weeks old on Saturday and I’m 23. Last night was the first time I’ve got out with a friend since I’ve had him and he stayed home with dad. I went to dinner, then came back to nurse and put him to bed around 9, and then after he was asleep went out to the bars. I ended up having 5 or 6 drinks and now I just feel guilty for being drunk like it doesn’t fit in with my new identity as a momma. I went out with a friend of mine who hasn’t been to town to visit for literally three years, and I know I should be able to go out once in a while but I just feel strange and really sad about it 😞 I didn’t miss any feeding times at all though since he sleeps until 6 am ish without waking.
