Sewing Machine

I have this Kenmore Sewing machine that my husband gave me last year cause he saw me sewing a lot of clothes by hand before. He told me he will get me a sewing machine so it will be easier for me but my problem is I have never use a sewing machine in my entire life before so, now im really disappointed whenever something will not work and had to read the manual over and over again just to make it right Its sooo Frustrating!!

Right now im working on my sewing machine cover to protect it from dust but again i cant get the inside thread to come out cause the upper thread is always stuck somewhere inside grr...
