Should I shave - need truth

[rreidu]

Hello to you all, my name is Radu, I am 30 and fighting baldness since 20 (when i first realized what's going on)
From 22 to 23 i took Propecia, it had great effects on my hair, but also "great" side-effects on my erections, and when I say great, I am not kidding. I am still recovering from the side-effects, but I am not here to talk about that.
Used some Minox for one year, had some effects, then I have quit (I really can't understand why)...started back again, now it got pointless.
From 24 I have started using Nanogen Fibres. In the beginning very little, just to give it a little fullness, slowly I have started to add more and more. At some point I have gave up trying to "rebuild" my hairline, and started leaving about one finger and a half empty and starting from there. These Nanofibres got me lasting through my twenties, but were also a nightmare for me. I am constantly thinking, does it show, will it rain, can people notice, no I can't come to the pool....I missed a lot of social stuff because of it. I wash my hair daily and apply, and some days I just wear a cap, when I know there is no chance I have to take it off.
I don't think a transplant is an option for me, because I am diffuse thinner, nor do I have the money for it, and I don't see the point to start minox again after so many start-quits. I am now at a point where I use very much fibres, almose my entire front hair is made up of them, I think it looks awful. I hate myself for not having the courage to just shave my head, but I think (for my skull shape) it will look even more awful, but i don't know what is worse, looking bad head-shaved or looking silly with you entire hair made of light-brown dust.
I am a master in applying the fibres, but they just don't have anything to cling on anymore. I haven't cut my hair in the upper area for almost an year (because last time I did it you could clearly see I am balding) I just cut it in sides and back, and relly on some length on the upper area for some coverage.
I am adding some photos, please guys, tell me what do you think, should I just give up and shave? This situation is driving me crazy. I was thinking to wait until next summer (although i sweared to myself...this one will be it) but I don't know if I can keep the illusion until then.
Please answer and tell me what you think...
P.S. sorry for mistakes...english is not my native language
