Guilty

First time mommy here,Feeling extremely overwhelmed and ashamed. For 3 years I prayed for a baby ,after 2 miscarriages ,God granted me my wish and now I have a 6 month bundle of joy! Oh god how much I love my lil Leo! I can’t seem to get enough of him, but here feeling some kind of way. After 11 days off of work and a trip to the beach ,first family vacation, I feel exhausted like I haven’t even been on vacation! And I feel like an ungrateful person! The whole vacation I had to sit on the side watching friends and husband have fun while I did my mommy duties. Loved having fun with baby at the beach and at the pool and juz being with him all day was great! Being Leo’s mom is amazing and I wouldn’t change it for the world so why do I feel like it’s been sooo much work? I can’t even explain wat I am really trying to say right now! I feel like I need a break but then if I even leave him for more then an hour to do anything but go to work I miss him so much and I feel so guilty for leaving him for selfish reasons. Oh guys idk what I am feeling. I must sound crazy and probably not making since but I just needed to vent!
