Foreverlonelygirl - I could list off some things like mindfulness and yoga and expressing creativity but you can get free advice anywhere.
I want you to know that you are not the only one going through a crisis. Everyone I know has some kind of crisis.
The most difficult thing for me to do has been to give up my childish expectations of living happily ever after. There has been much suffering in my life and there are no easy answers so I wake up to each day and try to find one treasure in the time I have today.
I will admit that mindfulness or meditating does help me feel a connection to within, but anything can be that for us.
If you want more info or just to share, feel free to PM me or post here.
