Update:

Thank you all for your replies,
I went back to my GP but she says by law she is not allowed to give me these medications, he either has to give it to me or give me a letter that says she can do it (which I had already requested in a previous email and he did not give)

Unfortunately due to Covid regulations I am not allowed to go to his office in person unless I have an appointment and since he isn't replying to me I can't even make one.

In the meantime I am continuing to contact other clinics but so far without any luck
