So frustrating

Pre pregnancy I was an avid hiker and backpacker. Hiking 10+ plus miles at a time with hundreds of feet of elevation change with a 40 pound pack. I went on a small hike/fishing trip yesterday; not even a mile and flat as can be not carrying anything and I’m so tired today and my hips and back are in so much pain. It’s so frustrating cause for the most part I feel the same as I did pre pregnancy but then I try and do something like that and I’m paying for it so hard cause I over did it. I miss the woods and trails so much. Being out really helps with my anxiety and now I can’t even do a small trip without it causing me to lay in bed all day the day after. Just need to vent sorry lol
