Could you correct my letter?

Dear Alice!

I didn’t write for so long because I’d like to surprise you. I believe it’s nice to surprise someone who lives so many kilometres from me. I kept your address in my mind because I wanted to send you something in the future when you weren’t expecting it haha. So… Here it is. Pity (don't use this word... try something else like "Shameful", you didn't decide to surprise me first. I hope my handwriting isn’t so bad; some people say I write like a monkey with a pen haha.

I'm writing to tell you about how I’ve been recently and to get to catch up! Please, tell me everything that has happened there recently.

I became more keen on website developing recently and I try to make one website to looking for snail mail penpals! I’m too weak in website programming however, I already have this ambitious project. I’m still a beginner in this hobby but I think I’d like to work with websites as a freelancer or for an agency in the future.

I am cofused

I love my family, I have four brothers and sisters (here I would use "siblings" or say "I have 3 brothers and one sister" of course fixing the amount.My brother went to buy a house recently, but he didn't have enough money .So I lend him some, but it still wasn't enough (I think this is what you wanted to say). I raised money many different ways for him.But the whole event he indiference,he don't express buy or no at last.Idon't know is it right or wrong.I am confused. 

I don't understand what you are trying to say in the blue part. The highlighted part shows what was fixed or could be fixed and in parenthesis is either saying why I changed it or how you could change it.
