very often catmagick we make big mistakes, from that point of realisation, everything seems terrible and irreparable, but understand, life happens, people get over things, and we find other things to drive us forward, send me a PM with exactly what happened, i will be more than happy to help fix where i can and just give advice where i can too. the past is the past and it is behind us. the future is unwritten and yours to make as you wish, even today is something you can make the best of.
I suggest donot mess with time unless you have very good reason (non-personal effects billions etc) and also it takes alot of energy and if it goes wrong either descrution or a bunch of tangles .
well i hope you learned from your mistake! going back in time is too dangerous, and can have bad conquences, and not just to you ,but to everyone, hang in there, and try to fix it here in the present, but if you need help don't be scared to ask for it you will be suprized to find people will help if only you will just ask.just try to do what you can to fix it now and don't get upset if it dosn't work the first time ,
in theory it is possible to travel backwards and forwards in time but only in particles lighter in mass than light itself, the trouble with the idea of a person doing it is that it would cause that persons reality to collapse, any changing of the past will have huge effects on the whole of the future.
We are all connected in a huge web of energy (that our anestors called Wryd) every action and thought weaves this web into the amazing pattern we call life.
in other words we weave our own futures through the actions of our past and present, our job in this life is to learn how to weave our webs the way we want it, by learning from the mistakes we made in the past and striving our best not to repeat them.
you are already half way there by admiting that you made a mistake and all you have to do now is try to fix and move on and make sure t does not happen again!
thats where magic can come in, by casting spells to guide you and if needed protect you and others around you!
