dehydrated skin and terrible makeup - need serious help

ive been wearing makeup everyday for 5 months now and i STILL do not have a solid routine because it looks horrendous every time.

my skin is dehydrated - very dry but also very oily tzone. i am trying to work on this, i know skincare is the root of it, but I also do not feel like i should be struggling this much with makeup.

i have really uneven skintone and need the coverage which is why i wear makeup, but it gets so oily so quickly and starts to melt and lose coverage towards the end of the day which looks horrible. i feel so embarrassed when people look at me because i know i look terrible.

like i said my skin is dry, and the regular oily makeup techniques just emphasise my horrible skin texture, and they dont work anyway. i feel like ive tried absolutely everything:

• all mattifying products
• all hydrating products
• a mix of both
• many different primers, foundations, powders and setting sprays
• no primer
• using powder and or setting spray before foundation
• less powder, more powder
• less spray, more spray
• blotting during the day

the list goes on.

i am not really asking for a product recommendation because i have wasted my money on so much just to get the same result.

i believe it must be a technique issue. my skin does not seem to absorb my skincare properly, and it is visibly 'wet' before i go in with primer. again, i have tried blotting this first but still no luck. i use a lot of hydrating skincare products too (toner, serums). i tried cutting out all actives for about 3-4 weeks but this didnt change anything.

i just do not know what im doing so wrong but i hate having to wake up and go through this nonsense every day. not wearing makeup isnt an option for me unfortunately because my skin is so bad, so i feel trapped in this.

any advice at all is appreciated, thank you. if anyone has had a similar issue please tell me what worked for you.
