It is always a difficult decision whether to take medication of any sort - it is about balancing the benefits and potential side effects etc.
My view is that if your life is miserable as it is, then why not try something that is known to help? OK, you may have some side effects; but on the other hand you may not. There are side effects to having your leg in plaster if you break it, but you would accept that.
My DD has been on citalopram for many years and it has been an absolute godsend and transformed her life. She inherited her Dad's anxious personality and it was blighting her life in a big way. Now she is living a happy life without these problems. She did reduce the dose a bit at one time, but found that she still needed it, so is still taking it - no side effects, only benefits.
I was on a tiny dose of a very old-fashioned anti-depressant to try and control my migraines. Following a hip replacement I became very depressed and the dose was increased - I am still on that dose as there has not been a good moment to decrease it when I have been free from life stresses - sick OH, problems getting his care, then his subsequent death. I am happy to keep taking it for now as it makes life much easier for me. Hopefully at some point in the future life will stop throwing manure at me and I can consider slowly reducing the dose.
If were in your situation I would simply take it and give yourself a chance of an easy and happy life. We are not getting any younger and it makes sense to grab what is left of life and do everything possible to enjoy it.
