Waiting for assessment stuck in a nightmare

Hello.. I'm new to the group and have suspected for a while that I am on the spectrum after working as an Autism Support Worker. I also have mental health problems and trying to get my voice heard is a challenge. Some of you have mentioned being passed pillar to post. My GP surgery doesn't seem to know who deals with Autism! But i finally (I think) have a referral.

I have lost jobs very quickly due to overwhelm and emotional breakdowns. I cry a lot. I struggle to cope with day to day life. Noise, bustle, people's tone of voice, thinking people are angry when they aren't, my mind going blank, not being able to multitask. I avoid people even at home with my parents. Yet I can come across as cheerful and articulate a lot of the time. 

I  feel my future is bleak and I will not be able to hold down a job. I am capable of much more but this thing is getting in the way.

I'm so worried i will lose my current job as a Health Care Assistant. My manager thinks because i am often upset i am not coping. She doesn't understand. The in-house trainer politely asked me if i had considered if i was autistic. I said yes and thought it was highly likely. So I put the wheels in motion.

I feel so broken and weird and frightened and confused and misunderstood. So I came here!
