Is this a job, or voluntary work?
Six weeks suspension seems a long punishment to inflict.
There must be a code of conduct for members and officials to follow. Ask for a copy, and also written records of how the decision to suspend you was taken, and the reasons for it. Compile the evidence for your case ; you do not have to use it but it will clarify matters in your mind.
Do not help the person filling your role, however much you value your club; you are being taken for a fool if you do and it may increase the poor treatment meted out to you.
Sometimes Governing Bodies make arbitrary decisions without being aware of correct procedures; this should be challenged.
At the end of my career there was a dispute over the date of my retirement. The Governing Body had made serious mistakes, had to back down, and were astonished to find they could all be removed for gross incompetence, that is, failure to read and apply the terms and conditions correctly. That simple.
This governing body may have exceeded its remit; they have certainly treated you badly and you should challenge them. Doing something practical will occupy your mind and make you feel less of a victim, and it is surprising how slapdash many people in what they consider to be positions of authority are, until they are challenged.
If you don't your feelings of injustice will fester and spoil your return to your club.
