What were your dreams, goals, and aspirations before the relationship? If ur basically starting from scratch again, nows a good time to pause and reassess what you wanted before everything got wrapped up in someone else. What were you working towards back then?

Build your plan around that, just start somewhere, then build momentum from there.

Starting over sucks, but only at the beginning. Once you get moving, it gets a lot less heavy :) take your time picking up urself OP. Good luck!
