Propranolol help

Hi everyone! Im new to this forum and im kind of in a desperate situation. I take inderal (propranolol) for my anxiety. First of all; it is the best thing i have ever tried. But the problem is, that i can tAke 80 mg per day and maximum 40 mg at once (instant release, which is the only one available here).
Now i need 60 mg for it to work. And then after 6 hours i take 40 or 50 more. That is more than my doctor want me to take. But im gonna switch doctors, cause she is really just awful. But when i take less than 60 mg my anxiety still cripples me to the point i want to give everything up.

Ive been taking it like this for 2 weeks now, no side effects. My pressure is perfect. My pulse is somewehere between 60-80 throughout the day. The MOST important note here is this: i have done a gastricbypass 5 years ago and i read in researchs that i absorb 30 procent less of drugs like propranolol than normal people. Maybe that explains why i need more of this for it to work. That means 60 mg : 40 mg for me. But my doctor dosent listen to me, she said that im switching doctors so i have to wait for my new one to get help.. it could take two months to get a new one.

Could this be dangerous? I really need to just know if its okey to do this right now since im having a hard time surviving this tough time and the inderal is the only thing giving me a break.. to sum it up: my body absorbs 30 procent less of propranolol than normal people. So im taking 60 mg inderal in the morning and 40 later. My pulse is perfect and i take it all the time. Pressure too. Can i stop worrying about this being dangerous? I just want to stop worrying about this and be able to take it and breathe a little from the anxiety but im scared.
