My singing has really gone downhill .. please help?

Okay, so.. at one point in my life as was naturally a really good singer.. I've been in many bands and have had vocal lessons to make my singing even better! Well, besides losing everything in my life that I live and care for over the last few years and being lost as a person, music has been the only thing keeping me alive in this world and might be the only thing that saves me and help me to get my life back together. I always get extreme offers to take part in music stuff. But I'm never ready. It sucks. My life has reached a downward spiral and now even my singing is going down the drain.. I used to aw ppl w my voice and was told to nvr give up bc it would be a waste.. I can't offord singing lessons anymore and it's been 2 years since I really sang bc I fell away from music. The last year I've spent trying to get my voice back but got nothing. I have like no vocal control or something.. I bought Brett Manning's singing success program awhile back when I had a job but I no help. I hardly have time to be alone and practice like Marilyn monroe says real talent is made when alone. Or something. I've even tried starting with myself bc it seems as tho I lack confidence.. I've even turned to listening to Wayne Dyer which kinda seems to help w myself but my singing is still off.. music is my pion..and I just wanna go at it full force! .. please please help.. thank you.
