Open But Very Guarded

I'll share a great deal of my life but I do have trouble letting others get close to me.... Been burnt a lot by love and family and friends... It's made me build a lot of wallls.... They're really tall mfs....Very few get past them... Even those that do take the time to climb have a hard time getting very close.... I only have a very few that really know me... Even then I keep a part of myself hidden... There is a very dark place no one can reach....
