Only way to cope with autism is to use dissociation

My only way to cope with my autism is to use dissociation. I only started getting this two years ago and as most of the research I did said that its over a stressful time I thought it was because of my mum getting a new job. But I have an under active thyroid and I then did more research and found out that the pills I was taking (levothyroxin) could cause dissociation. Recently over the Xmas break I have been out of routine and so have been forgetting to take my pill. Cos of this I have been having angry meltdowns increased anxiety and heavy mood swing which since taking the pill to dissociate out I haven't. I'm now back on them and have return to a more neurotypical person. With dissociation I feel like I'm in a dream and often can't remember or have no idea what people are really saying to me, to some the is a very bad mental illness but to me it makes me better and it is the only way for me to cope. What do you guys think should I get this checked out and stopped when I'm a better person with it ? Does anybody else have this I'm so confused and really need some answers? Love Lily xxxx
