Wondering what’s going on with me

Hello ladies, I was diagnosed with PCOS a little over 2 years ago. I still do not fully understand it and what happens with it but I do know that I get all of the symptoms like everyday and I’m just over it and I don’t know what to do, I’m constantly depressed and I have the worst anxiety about the smallest things. Also the past 2 months or so I’ve been feeling so sick to my stomach in the lower area and it’s so painful and sex has also been painful lately, to the point where I tell my bf we have to stop because I am in so much pain. I’m also overweight and have multiple other health issues such as hypothyroidism, asthma, and hashimotos. The past 5 years have just been so overwhelming being diagnosed with all of this pretty much all around the same time and I’m only 18 and I’ve also been wondering for when the time comes and I’m ready to start a family about having kids and if it’s hard to get pregnant? I’ve been on birth control for about 2 years now because my hormones are so out of wack but I stopped taking it about 2 months ago just because I was constantly feeling so sick and not myself. I’m just looking for some support or someone to talk to about what’s going on with me and what to expect :)
