Depressed and confused in my life

Options
I am totally depressed right now..i have no idea where to go...today i completed my 4 months in gym..which helped me losing 107kg to 77kgs...I have even bigger issues to follow now :(

I do look fine but i have some loose skin around my arms and a littlebit of tummy which needs to be flattened...


Now problem is how to do it? i dont know what to do..biggest problem is i dont have financial support so i couldnt pay my gym fees.,,i have a gym where the owner allows me to use it without paying but theres no trainer there and the owner himself doesn't know anything else and the worst thing is gym doesn't have all machines infact got only few...i dont even know exercises of chest which are common..so theres nothing i can do it alone:/

In short all ii need right now is an friend who can guide me...how to remove that loose skin around arms and flat tummy+ weight lifting tips :/
