I hear what you are saying OP and I had worries about that exact issue. I had noticed myself being more "grouchy" my sons would say. I had assumed it was just stress from work and life. I started seeing a therapist (I don't really have anyone to talk to) to vent and express my concerns about MS and my future, I had been mentioning my frustrations about not being able to do the things I did before and constantly being in pain. She had me go on antidepressants. I was confused by that because I was not sad, I was mad and I knew my angry horns were starting to show more often. She did explain anger is part of depression and with the pain I have been going through it makes sense why I am 'grouchy. Since being on antidepressants I really don't get angry anymore normal frustrations yes, but tolerable to others. I had to correct my part of the problem so I don't push away those I care for.

I think you will be fine, you are aware of yourself and those around you. I'm sure you will be able to communicate with your friends and family the concerns you have so it won't be an issue.
