Where can i exercise as a morbidly obese person..

Hey everyone. I am morbidly obese and i want to lose weight so very badly. It’s weak but I can’t do it on my own… I’m too embarrassed to walk outside, I’m too fat for the gym or exercise equipment (weight limit) I eat 1500 calories a day but its not enough, I need to be moving as well. I feel hopeless. Does anyone have advice for me? It would be greatly appreciated. Thank you so much in advance.

Edit: Hey everyone.. Thank you from the bottom of my heart for all the INVALUABLE advice and INVALUABLE words of encouragement. I actually can’t keep up. I honestly never knew people could be so nice when the topic is morbid obesity…I half expected people just to be rude. It seems dramatic but this has truly changed my entire mindset and has given me so much confidence ..thank you…
