Don't give up. Try to give yourself some space. Sounds like you really need some breathing room for a while. Honour yourself and the rest will fall into play. Take all the time you need to centre yourself before you expect to know what steps to take next. "The next steps to take are always clear in time to take them." Give yourself time to prepare your mind to think clearly. Then you will be able to see the next steps you are to take.

Trust that it will work out in time for you and your friend to resolve the differences and preserve the friendship. Give it time.

Wishing you well..... take good care.
