Hey, man, I'm just about 5ft, so I get it. It gets me down at times, but can't control it, I'm 21 so I'm for sure done growing. Yeah, with testosterone you might be able to grow more; I've heard of a good few people growing a little bit, so I'd imagine the younger you are, the more you can grow.
I'm sorry if it angers you, but just have to say, height isn't really the be all and end all. Yes it gets you very down, I get it, but when all is said and done, there ARE short guys. LOTS of them. And they can have normal lives, it's not like a severe disadvantage to anything. Society is stupid in that being short is seen as less desirable as being tall, I know, but people will always find a reason to judge you or look down on you in life, so no-one, not a single person, will be able to escape that. Hopefully you could learn to accept your height if it does happen to fall short of your desired height. And I don't say that to make you angry, I just say that because wanting to die is such a horrible feeling, and so I just hope that if it didn't work out ideally, you could learn to be happy in spite of it, because it is possible. I'm not speaking for myself, because I'm still working on not hating myself, but I know it can be done.
I hope it does give you lots of growth, though, it's not impossible, not by a long stretch. My brother's a giant and he's still having growth spurts even though he should be done growing by now. I think he stole my growth spurts, personally lol.
