You can drown in shallow water if you refuse to stand up.

Some difficulties are survivable the moment you change position, and the drowning is a matter of refusing to do the obvious thing. That refusal usually has a reason, pride or exhaustion or not wanting to admit the situation, and the reason is understandable while still being what is holding you under.

Ask whether the thing overwhelming you has a simple action available that you have been declining. Asking for help often is that action. Standing up is not a small thing when you have been under a while, but it is available.
