Feeling discouraged - Bariatric patient

I had Bariatric surgery done in January 2022 and got pregnant with twins in 2023, all the weight I put on was in the last 3 months of my pregnancy. 50lb in 3 months almost half of what I eliminate after surgery. I’m feeling so tired and disappointed with myself, it’s being really hard to get back on track and take care of me again. Has anyone had the surgery, put on weight during pregnancy and lost it after? I’m 6 months postpartum
