I Have Been Working out for 2 Months and I Feel Like Giving Up……?

I'v been working so hard, working out 5-6 days a week, an hour a day.
I do 3 days weights, and 3 days Cardio.
I'v pushed myself more than I ever have done in my life for this.
The thing is i cant see any results!
And its making me feel demotivated and kinda upset.
Im on a strict diet consisting of salad, tuna, meat, fruit, veg, etc…
I have only lost 3pounds in weight in 2 months, and my muscles do not seem to grow.
I guess I might be the kinda guy who developes muscle REAL SLOW, and takes ages to lose weight.
I dont know, but thats what im thinking.

I mean, I can feel the difference in my arms and chest, but I cant see it.
Also, I feel alot stronger, for example, I can now do press ups, which i could never do before, and the biggest change is that i can now do chin ups, which was impossible for me before.

Its just after 2months of intensive working out, I can barely see any difference, and I've only lost 3pounds.
I just find it weird, I really expected to see a difference, and now Im just feeling demotivated and feel like giving up my workout routine.

Should I give up???

Suggestion:

Id say what you should do, is take a week off from the lifting weights. if youve been going at it that hard for 2 months your body may need a break. What I would do is take that one week off, then when you go to workout dont use the same routine as you were before, try to switch it up a bit. this will confuse the body into creating more muscle. Rest is key when it comes to lifting
