I feel so alone

I have been waiting 14 months now for a referral for my now 3 year old boy. It is very clear to us that he is on the spectrum and needs help but we haven't gotten any and it is really getting to me. I just want to help my son but I feel like I am not able to anymore. I really am hoping that we get the call soon because I just think the longer we have to wait the more he and us as a family will suffer for it. Been feeling really down the past couple of weeks and have literally just had a full on meltdown on the way home. I just need help.
