Lost the last 5 games, what am I doing wrong?

With all due respect, I have analyzed the games without any time pressure and I still don't understand how I'm losing.

You don't even have a game rating, and your puzzle rating is bad. Why should I listen to you?

All the time in the world is useless if you don't know what moves to make.

As said, I analysed the games (slowly) and still didn't learn.

This is basically trolling now, you aren't listening to me so please don't comment on my threads. Thanks.

He answered your question....and it's the best answer you're going to get. Slow down your game play, or continue losing and wondering why. 

Patrick, just because the guy has no rating and low puzzle ELO, doesn't mean he can't bring something useful to the table. Also, not a lot of people are helping players here, it doesn't hurt to be a bit appreciative of the little attention given, but I digress.
Besides what has already been established by the other players, I can tell you that if you want a more in dept look on why you're losing, we will need to see the games in question annotated. That takes a while, but the feedback you'll receive will definitely help, I guarantee it.

This advice is sound on paper, but it is not good when you actually look at the guy's games.

He is trolling. Both in the games and in the forums.

Please have a bit of kindness, what do you mean I'm trolling in the games? I assure you, it might appear that I am just losing but I honestly am trying my best. It would be helpful if you could explain your comment please.

The reason I don't take long to think is because my opponents are taking many minutes to think so I utilise that time to think of my own next move. I have thought through my moves thoroughly but I still lost, therefore I am clearly missing something. The 2 games you posted were where my connection cut out or I resigned a losing position. I have since lost about 15 games in a row, I don't know what's happening to my game but I could really use some help. The fact that the forums have all ganged up on me because some 1200 posted an original comment about time management is really frustrating. I moved to 15/10 games to give me more time but the fact is, the moves I selected were what I thought was the best move. So I need help explaining why that wasn't the case, not some sarcastic comment about playing 'speed chess' which I certainly don't play.

I've been through and looked at my last 13 games. Here are my findings.

Most of these issues are not blunders, I have no idea how to avoid them. It seems like I am playing good moves until I suddenly discover I don't have enough pieces to defend everything, usually during the late opening (move 8-15 let's say). I am simply being outplayed by my opponents every single game.

Actually, the 2 games that I linked were the same: you resigned in an equal position.

Here is another:

This is a completely losing position, I was destroyed in 5 moves, lost the center, no development, what's the point of playing that position?

Ridiculous.

My guess is that you are sandbagging (which is against the rules, mind you). The reason why you expose your cheating via repeated forum posts is unclear, I have to admit.

Please if you are going to comment on a game comment on these, these are the ones I don't understand:

Are you for real?? The engine says it is losing, the center is completely lost, I fell for the gambit. In what way is that position worth continuing?

Game 1: you hung a piece by 12. Qxf3?? after "thinking" for 3 seconds.

Game 2: you lost a pawn in move 10 then you lost a piece later. It is actually okay, it was complicated. However, as it was complicated, why did you not spend time on the game? In most of the game, you had more time than you started with.

Game 3: you lost by the insane 10. - Qf6??, putting your queen in front of the discovered attack. Next move, you have a lot of unappetizing options, so you choose the worst, to throw away the queen, again without thinking.

Game 4: your opponent made a quite dubious piece sacrifice, which is still quite dangerous in speed chess. Then you played 17. Qd2 that hung a piece and got mated.

Game 1: you hung a piece by 12. Qxf3?? after "thinking" for 3 seconds.

Yes but gxf3 is also losing because the king is completely unsafe. I already lost prior to this point.

Likewise with Game 4. You are saying the sacrifice is dubious but as far as I can see, it completely opens up my king into a losing position. If my King isn't defended at all, isn't the game lost?

In. game 1, after gxf3 black is better and the game goes on. After Qxf3 black wins immediately. The two options are not equal, not even close.

It seems to me that you are using this "I was lost anyway" argument to give yourself excuses for ridiculous blunders. And those blunders come from the fact that you are not thinking, you just play semi-random moves extremely fast. You also like to resign in postitions that are slightly unfavorable or even completely equal.
