"Whats best way to get out of this"
Get an IMC Rating, get access to a decent plane, keep current to use it. (This raises other issues e.g. that most airfields don't have an instrument procedure and one still has to land eventually)
Otherwise, don't fly if any actual+forecast cloudbases en route are below the MSA. (That will stop you going anywhere on most days.)
Otherwise, do a 180.
