Anyone want to help me feel better about weight after baby

So, I just had my 3rd baby, I am three months postpartum. Feeling incredibly discouraged. I had all babies in three years at 23, 24 and then 25. I started out weighing 120 when I got pregnant with my first. First and second babies, no stretch marks! Third baby, I got up to 208lbs and have stretch marks all over my body.

I feel a little bit discouraged now. Not only does it make me feel huge but I can't help but hate the stretch marks, even though they were part of having my daughter. Does anyone have any success stories about getting back to normal size after? Or at least want to make me feel like this is normal and will pass? I'm down to 155 now but still have so far to go and just seem...stuck.
