Flight Attendant reported they were too fatigued to work after getting 6 hours of sleep over a 50 hour period due to company scheduling policies and flight delays.

Narrative

I'm sorry this report is coming in so late. It took me a while to recover from the symptoms of sleep deprivation. I had in order to compile a report; and I also had to keep working my schedule on top of it all. I had to call out fatigued for my very last reserve block. I didn't want to risk getting called in due to how exhausted I was from the lack of sleep I had due to so many operational errors I had on my pairing. Two hour call out Date; flew all night through ZZZ1; where we had a 2 and a half hour ground time. My entire crew tried to sleep on the plane; but couldn't. The plane was very cold and outside the airport was surprisingly pretty noisy sporadically. We got to ZZZ and we waited for our hotel rooms for over two and a half hours. I had been up for over twenty hours at that point. Crew scheduling is zero help. I told them I was exhausted and my layover was getting shorter than federally required but layover times don't change if you're stuck without a hotel room according to them. I already had a short layover to begin with; so I ended up getting to my hotel room at XG:30 (we had been at the hotel since before XE:00) and was back down in my van to the airport at XP:10. We then sat on the taxiway for over an hour for weight and balance numbers; then our pilots timed out. Went back to the gate; and unloaded everyone but 3 passengers. Then we managed to leave around 11pm with new pilots. In ZZZ2 deplaning took over 30 minutes because of wheelchairs and an aisle chair. I was home by XA:00; and was going to be on call for the remainder of my block at XL:00. I should have called out fatigue in ZZZ retrospectively. But then I would have just been stuck; stranded again at a hotel with no rooms; for who knows how long; again. The hotel was overbooked and we found out they were just waiting for other crew to leave so that they could flip those rooms and give them to the new crews coming in. During my extensive ground time on the way home from ZZZ I calculated like 6.5 hours of sleep in the past like 50 something hours? I feel so panicked about calling in fatigued again; I've felt bullied by the point system and honestly in the past bullied by scheduling too but I was at a breaking point with this past trip and I was just too drained and exhausted that I had to call in. When I was sitting on the tarmac in ZZZ before we returned to gate; I got a notification that they had tagged me for a DLG/BET the following day and I cried in my jump seat. I also cried when the pilots timed out and I cried a final time when they left pax on board. I've never cried so much at work ever and I definitely think it was just pure exhaustion but it was so embarrassing and I hate being reduced to that. All because I was trapped working a horrible pairing. I know life isn't fair but feeling like I'm supposed to suffer relentlessly through these absolutely gutting trips to be considered a good employee is just so hard on me mentally. I'm really trying my best; I know it doesn't look that way on paper but I am trying. Stop allowing two hour call outs for all nighter flying.
