I gained weight!

Oh no! I gained weight!
Healthier lifestyles - No coffee, have proper meals (I started taking breakfasts and dinners), and I have stopped taking icy drinks. Didn't know that I actually gained weight by practicing a healthier lifestyle! Should I stop? Should I?

Dear was saying the other day, "I am such a good example for others cos I have lost so much weight, but look at you! Look at your stomach! Aiyoh... How am I supposed to take you out and tell others that you are my spouse?"
T___T
I was so sad after I hear all these words... Why it takes only 2-3 weeks to gain weight, but it takes forever to lose weight?

What should I do now?
Should I start taking coffee again?
Should I skipped my breakfasts and dinners again?
Wanted to go for sauna last Saturday in my Condo, but saw a "under treatment" memo in the sauna room... I think I need to start exercise! 30 minutes a day! I need to go to the gym and workout! I hope I won't see "close for maintenance" memo in the gym room. Otherwise I am going to complain! Paid maintenance fee monthly, but these cannot be used and that one out of order! What is all these?

I must control my food intake.... must eat lesser from today onwards...
I cant afford to gain more weight!

Oh ya... I need to 'replenish' my skin care products...
Should I top up what I am currently using? - Clinique 3 steps
Or should I change to Biotherm or maybe SKII?
My mama is using SKII, I feel like using it too.

So, what is your opinion?
