I feel so lazy 😭😴

I guess I just need to vent... I’ll be 30 weeks tomorrow. With my first pregnancy (our son is currently 19 months old) I was active throughout. I had bad HG but was able to muster up the energy to go for 45 minute walks on my lunch break daily, did prenatal yoga once a week, light home workouts pretty much daily and bike rides with my husband on good days... this time around I feel like I am under a constant fog of exhaustion. I was on modified bed rest and pelvic rest from the time I was 12weeks to 20 weeks because of a SCH and then it took me a few weeks to trust that any kind of activity was not going to endanger my baby, but I haven’t bled in over 10 weeks, I’ve been cleared for all activity by my OB etc. And yet all I want to do is sleep! Because of covid I am now at home alone with our son all day, every day. I love him to death but I’m exhausted just trying to keep up with him all day (he is a very active and adventurous toddler - which is amazing but so tiring). I feel so guilty and lazy. I try to go for walks every day but only manage about 20 minutes a day and I plan on doing at home workouts when our son naps but that usually only happens maybe twice a week; the rest of the time I choose to take baths or lay in bed because I’m just so tired. I feel huge and I’m afraid that I will keep gaining weight uncontrollably. I’ll be 38 years old when our daughter is born in July so I’m also terrified that I will not be able to “bounce back” as easily as I did with our son (though I was old then too 😂). I have no one to talk to about this because everyone just thinks I’m being ridiculous. But I can’t shake the guilt of my laziness and like I’m not being energetic enough for our son 😭
