Lack of therapy and antidepressants

So last year I was diagnosed with depression after multiple incidents w/ self harm. I’m on the waiting list for therapy but apart from that nothing has really been done about it.

I haven’t been given antidepressants and I feel like my parents ignore it completely. I can’t go to the doctor and get a prescription for antidepressants because you have to be 16 to do that so I’m kind of stuck in what to do.

My friends are all pretty depressed as well and I don’t like talking to them anyway and my girlfriend has her own problems to deal with because she has asd and anxiety so I don’t know what to do.

The past couple of weeks have been some of worst for depression. I’ve just felt so down and there are so many times that I just want to self harm again but I don’t like talking to people about my problems so I rely on strangers on the internet because no one really knows who I am... any advise?

UPDATE

my mum is now acknowledging my anxiety and brought me a weighted blanket which is supposed to help people with various different mental disabilities
