I don’t know what to do

I honestly just hate how i look 
I always have been envious of others and how athletic and fit try were compared to me and it’s an issue that still sticks with me to this day. 

Ive been working out and exercising for up to 5 years and it always seems like I have made little to no progress in it 
Im still 17%  and still around 60kg 
I haven’t gained any definition or made any improvement at all 
I haven’t improved my midsection and I haven’t improved in anyway in terms of strength or pr’s 

I know I can’t give up and realistically I’m never going to stop but honestly I don’t even know why I bother anymore with it.
Im not even capable of doing any basic things.
I just always feel like I’m never good enough and it all Just goes to show I cannot do anything and im wasting my time. 
I’m aware of progressive overload and that I have to increase intensity and everything but everything time I go up a weight it always resulting in me not being able to lift it doing in in really bad form. 
Diet for me has basically been the same high protein stuff I’ve been doing for years and but honestly nothings really happened 
I’m just so fed up with everything atm 
I probably sound like a baby.
I’ve been working out consistently since I was 18 and little to no progress has been made
