Comfort zone is killing me

I’ve gained 50 lb after having my first baby and I really miss my old body, but I hate eating healthy and working out. Especially now being completely isolated with my 3 month old and not returning to work, going out, or seeing any of my friends. I just don’t have any motivation. I sit at home LITERALLY every day. And I honestly don’t even mind it, I like it too much. I was an introvert to begin with but since the pandemic began its made me even MORE introverted. And I’m eating pretty much whatever I want. I’m baking all kinds of desserts, making comfort food for dinner almost every night. When my fiancé gets home from work and the baby goes down to sleep for the night, we will watch movies and eat candy or snacks super late at night too. Before quarantine I was working full time and always making time for my friends. I was active. I used to go on morning runs and would go swimming. We used to have someone come and clean our house once a week. I went to bed really early and woke up at the crack of dawn. Now I like that I’m never on a schedule. I love staying home and getting to clean, cook, eat, play with baby, and just be a mom. I don’t feel like I’m being healthy though and I’m just really happy, or comfortable, in my comfort zone. But before I wasn’t really happy. I felt like I never had any time for anything. Like I hated how much time me and my fiancé we’re apart because we both had very demanding jobs and worked opposite hours. And I hated eating healthy boring dinners/lunches 24/7. There was no joy or spark in our lives. I was very confident in my body though and now I’ve definitely taken a hit in my confidence level. I used to post pictures and do vlogging videos, but now I’m way too embarrassed to put myself on camera. I still take a ton of pictures with my daughter for memories but I NEVER share them on social media. And the occasional times that I do go out and see someone I’m embarrassed at how my body looks and the fact that I’m not doing anything about it. It’s like I’m stuck in my comfort zone and I need to find some kind of balance. I really miss making videos and sharing pictures of myself on Instagram. Is anyone else struggling with something similar to this?
