Hi Blacky,
I was on T for 6-7 years. I stopped a couple of years ago, continuing to live as male. I completely understand what a tricky decision that is, and the associated pros and cons. In my case, it was a combination of a variety of things, though looks were one of them - more detail about my decision is in
this thread if you are interested. How old are you? Your age will impact how much that period on T will affect you long-term.
If you stop, your voice will remain masculine (though may be a little higher without T) and you will retain any body or facial hair and clitoral enlargement you have developed. Your face and body shape and skin texture will refeminise and you will begin menstruating again (menstruation is a big emotional hurdle for a lot of guys, so this is something you will definitely need to think about). You will need to give some consideration to yout emotional comfort level with those last few things and if you are likely to be able to deal with that if you have difficulties with mood. Also, were you able to pass as an adult male pre-T? If not, have you developed sufficient facial hair to help you pass? Facial feminisation may mean you struggle in the long-term not to look like a teenager (this is a big issue for me!). And although this is a short-term thing, being deprived of T after that amount of time will not be an enjoyable experience - you may have noticed already that if you are late with your T you experience low mood and lethargy, which is a symptom of your body being short of hormones. If you stop T you can expect to have to deal with this for a while, while your body gets used to producing female hormones again. How long that takes will be different for everyone, but for me it was about 6 weeks before I felt like I was functioning normally again, though I had been on T for a long time.
In my case, stopping was the right thing and I'm happy with my decision. On the other hand, I don't think I would have stopped after only two years. It took about five years for my facial hair to fill in sufficiently that I looked like I had much beyond adolescent scruff.

I now wear sideburns and a chinstrap beard, and I need that - I have a feminine babyface and without them I'd be struggling to look like I was out of high school, even though I was on T for so long and am in my early 30s. I also found that living as a man on T for so long had really chilled out my feelings about my gender, and for me it was worth that time of emotional growth and adjustment. I grew very comfortable and secure in my role as a man and no longer felt the kind of distress or dysphoria over the feminine aspects of my body that I once did. If you are concerned about the effect on your mood and T helps you, it may be worth staying on T until you feel like you are in a more emotionally grounded place. You didn't mention how you felt about menstruating, but I will add since I think it's relevant that my uterus is a great deal more agreeable than it was pre-T. I used to have cramps and mood swings and menstruation lasted 5-6 days, but now it's generally only a couple of days and I can't say I've experienced noticeable cramps or mood swings since stopping T at all. It may be because I'm older and more relaxed in general, but despite the estrogen, my moods are pretty chill, just as they were on T. I haven't noticed stopping have a big impact on my emotional state.
I hope this helped - if you have any specific questions for someone who's had the experience you're welome to reply or PM me.
