I am so stuck in the second year of my PhD. Should I leave?
I suggest first to ask your Prof-A explicitly for more meetings, particularly also for a time and date for the next one at the end of the previous meeting. Maybe Prof-A doesn't realise that you are in some kind of &quot;crisis&quot;. You should also tell them clearly that you feel stuck and that something needs to happen to get you back on track. All else I'd let depend on how that goes.
As a supervisor I'll normally do meetings with students when they ask. If I haven't heard from them for some time I will try to find out what's going on, however professors are usually busy and may not necessarily chase up students who don't care for themselves. Your Prof-A may just believe, somewhat conveniently for them, that all is fine, unless you tell them explicitly otherwise.
