Waiting for a diagnosis - what can I expect? How do I prepare?

Hello all.

I am a new member here and thank you got opening this site to me!

From my understanding, I have all the symptoms of MS: paresthesia in fingers, severe fatigue, headaches, visual disturbances, strange sensations in my legs and arm, itching... you name the MS symptom, I probably have it. 

I need to have an Electromyogram (I think I spelled it correctly), but I am almost certain it is MS. The paresthesias has been there for over 4 months and for the other symptoms it has been for months to years!

I have to have a minor orthopedic surgery in about month on my elbow. I am afraid of this operation. 

Again... I am fairly certain I have MS.

As a result of all of this, I have been very depressed and moody and thinking about it and the future only worsens the feelings of depression, anxiety, and worrying.

I am alone. No spouse, no children. I do not want to talk to my immediate family about it either, like parents and siblings.

Exchanging with people who have MS and are living with it can and will definitely help me feel less alone. I hope to talk to you all soon through here.

Feel free to comment and let me know what I could expect in the future, how to deal, etc. Thank you!
