Seriously when is it gonna stop

I'm tired of being tired... I have been taking Tamoxifen for about 8 mnths now and I hurt almost all the time. My joints hurt, my muscles are sore and sometimes my mouth still gets that raw hamburger effect, along with almost constant jaw and teeth pain. Granted this is nowhere near the misery I went through with chemo but enough is enough. I had one of my doc's suggest I stop taking it for a little while but I have a 1 and 8 chance of getting this stuff again and I can't see how stopping is going to help in the long run. Not to mention family members, who have never had cancer, who are looking at me and telling me, I need to just get up and start moving, yeah... I force myself to do the things my family needs done but usually by the time I am done, I am hurting so bad and am so tired, I feel nauseous, so I end up going to bed for hours until I feel better and even when I get up from this I am so sore I have to move slowly until I am loosened up. I am feeling a little better more often but seriously 5 more years of this, I think I might go crazy. While I on this rant I might as well say I also tired of being scared, if there was something else wrong with me, I am to scared to go to the doctor because what if the cancer is back or spread, talk about feeling nuts, I'm even scared to go to the dentist because what if the pain in my jaw and teeth is cancer. I also have people who are really trying to help by suggesting vitamins, lotions, and herbs but what they don't realize is that a lot of that stuff that is hormone rich and I can't touch it with someone else's breast. I get tired of having to explain that one to people. As big as this disease is' a great number of people have no clue about what breast cancer really involves.. Thanx for listening to me rant here, I think I would go crazy if I thought I was truly in this situation alone. As much trouble as I see here on this board from time to time, I have found a true lifeline here with you ladies, so (((())))) to you from me.
