God, I need some guidance

how do you ever know what you want in life? who's to say this is what your supposed to be doing. all my life I've been told to pray for what God's plan is for my life. i don't do it everyday and sometimes i go months without thinking about it or praying about it. but i feel like I'm that person who never knows when God's talking to me. i can never decipher my own thoughts in my head or if maybe that thought was placed there by God and that's His answer to my prayer. I feel like maybe I'm not close enough or i don't deserve to hear from Him. i need to know what my purpose is in this life. i need to know whats going to make me happy everyday. I'm tired of always worrying about making the wrong choice or decisions and not being in His plan. who I'm suppose to be with, what career I'm suppose to have, where i should be living. I'm so confused.
i just want to do what is right. i want to skip the nonsense and get on with what God has for me. this world really has nothing to offer me. i need to find a new church. i need to get back into being in His presence. my life is constant haywire these days, i feel all out of sorts. like I'm searching for something, but i just cant figure out what it is. i was so close to God this time last year my life felt right, it felt like it was what it was intended to be. then all of a sudden everything flipped scripts again. i just don't get it. i just want to start fresh and new, although I'm not quite sure what that even truly means.
i feel so unworhty and undeserving of anything God has to offer me. i make mistakes every single day, usually the same mistake over and over again. more so these days than before. I'm going to try and get my life back on track. starting this Sunday i am finding a church to go to. even if i have to go by myself!! its the last days and i will not be left behind!!
