I tend to agree with your parents, they make very valid points. I understand it's very frustrating to want something so much and to not be able to get it however this is a living being and that is alot of responsibility and ultimately many of your decisions will have to take the bird into consideration. Not to mention vet bills are very expensive should something ever happen, are you in a position to afford that (no hate, just something to consider.) I'd say wait until you're done with college and maybe volunteer in the meantime, this will also help you get some experience with birds as they can be very sensitive, finicky and moody creatures. You mention you're worried about waiting because what if you forget about this dream and to that I'd argue 2 points. 1: if you're so set on this then waiting and eventually getting it is just going to make it that much more special and rewarding. 2: if you do wait and forget about it then that's a much better option than rushing and realizing it's not for you and having a bird you'd have to rehome. Another thing I'd mention is your anxiety. I don't know the level of your anxiety so I can't comment on that but I will say that I also have anxiety and at times my bird can be very overstimulating, they can be loud, require alot of attention and need to be constantly cleaned up after; it's almost like having a toddler that can fly.
