Hi BexShez welcome to the forum
I'd say you are very early into this, and certainly by no means expected to be able to cope. In fact none of us cope with this every single minute of every single day. Even very long termers like me, 40 years, find that there are times when its all too much and sob buckets.
What tends to happen is the bad days get further apart, but never go away. So whereas in the beginning you might cry every single day and find every day so very hard, it will get to a point where the bad days come months apart, and the upset can last only a smidge of time. There is nothing to say you need to have reached a certain point by a certain time, it all works through, as and when.
Unfortunately no-one from anywhere can tell you how much hair you will lose, how fast, when it will come back etc. And that means absolutely no-one. Alopecia works to its own timetable, it doesn't follow that what happens for one person is an example for another. The variations in the condition are huge.
Stress is not good for us, it will just make us feel rotten - but at the moment medically speaking there is no known cause for alopecia. Many reasons get put forward, but at the moment they are all personal opinions, which may well be true, but so far not able to be proven. There isn't even an agreement of the time when an event happens, and the hairloss. And hairloss happens to people at the best and worst times in their life, to tiny babies and mature adults - there is no sense to it at all.
But whatever happens, whatever is needed, you will find people here who understand and who have the experience, so read around lots of information on all sorts of things.
