Should I decide on my dose myself despite doc's recommendations? Am I doing stupid shit?

Last time I checked my hormones my test was >1100 ng/dL so doc said to lower my dose. Initially I was prescribed Sustanon 250 once in three weeks and my doc told me to do my shots every four weeks instead.

In actuality I had switched to DIY testosterone enanthate about a month before I checked the hormone levels. I started injecting 100mg per week cuz that's what my bodybuilder friend recommended (he isn't familiar with trans healthcare, he just a roidhead). I was afraid my doc would scold me for going DIY so I didn't tell her anything.

After I got my testosterone results I became worried bc I was afraid of aromatization like hell. I changed my dose from 100mg to 87,5mg to 75mg (0.4 mL to 0.35 mL to 0.3 mL).

About two months have passed since then and I feel like I'm turning back into girl. My acne improved a lot but at the same time I feel shit and tired, my voice feels not as deep and buzzy as it was, my feet are constantly cold again.

I fear I might be underdosing myself but I also fear getting overdosed and having my test aromatized into E. And idk what I should do. Should I increase my dose by a little, like back to 87,5 mg, or go right up to 100 mg?? Atp I'm just deciding my dose from vibes only.

If it's important when I did my tests they only showed me my total testosterone levels, no free testosterone, SHBG or E2 for some reason (although I asked them to do them as well). I probably should do a full test on my levels but I'm in a tight place budget-wise rn.
