Welcome Grizlee.
Any time your physical health may be at risk from withdrawing, it is best to consider a medically supervised withdrawal.
For you, I would really encourage this, considering you are having liver problems. With symptoms that come along with severe anxiety and panic attacks, it may be hard for you or someone else who is not medically trained, to assess if you are in a true medical crisis.
Blurred vision can be from a panic attack or a medical emergency. You need someone who can assess your vital signs and make that call. Being in a controlled and professional environment may also help lessen your anxiety, knowing if something happens there is someone there to help.
Please consider a detox centre. They can also put you in touch with the proper tools for continued success. The wonderful supports of SR will be here, but you need to look after your physical wellness first.
