Cannot tell what is wrong? Is it normal?

Deflation

OK, ill try to answer some questions here. I apologize for the confusion. Im not very experienced.

My tree is a small juniper, and i do not know how old. Im guessing anywhere between 3-8 years (how do you check without cutting it?) During summer and fall, it is always outside, day and night 24/7. I never bring it in. It finally began to get cold end of November/ early January. Cold being a little below or above freezing, at night. It has yet to get that cold during the day. Towards the middle of December it dropped lower at night, and when it got below 25 degrees farenheit, I would put it in our garage, which I guess gets down 40-50s depending on the outside. Then, when I woke up in the morning, it would go back out. During the day it stays on a screen porch, where it recieves sunlight all the time, and there is not much wind.

I guess my mistake was watering it 1-2 times a week, and not checking for dryness. That makes sense. I was afraid it would freeze some days. When i water at this time of the year, I will bring it in, water it, and put it back outside as soon as I am done. It is just really cold to stand out there and water it. Is this bad? Our inside temp is about 65-75 degrees.

At the beginning of December we went through a period where it was just really dark clouds and rain for about 2 weeks, no sun. After this, I noticed that my tree wasnt as colorful as it used to be. It used to be very bright bright green, and very pretty. Now it is dull green and some leaves have brown tips (but not a lot).

That is what got me worried. I am probably too worried than I should be, and im sorry. Ive just never gone through wintering before and was a little anxious.

I also am sorry for the pictures. I was afraid they were to big to put here, and I also show them to my friends, so I figured it would be easier to just do it that way. All at once.

I now have another question. The next 10 days or so are supposed to be really nice warm weather. During the day, sunny and between 65-70 and at night around the 40s.

No doubtedly it will get much colder come Febuary and March, as it always does here, and I hope this wont cause any damage to my tree. But it being so warm here now, and then it might get freezing cold later, Im worried this might throw my tree off. Anything I could do?

Thanks a lot for the help guys, I appreciate every bit of it, and im sorry I caused a mess.
