HI, thanks for using healthcare magic
Lack of energy, difficulty concentration and anxiety are likely linked. Anxiety is commonly associated with depression and these conditions can cause these symptoms.
Treatment for anxiety and depression includes medication and
counselling. Unfortunately none of the medication is over the counter.
Heavy period flow, clots and severe pain may or may not indicate a problem. In some persons it may be due to fibroids,
endometriosis, infection.
The use of oral contraceptives may help to decrease the blood flow and control the pain.
Medications such as cataflam, naproxen or ibuprofen can be taken three to four days before the period as well. When this is done the pain is usually less.
Acne can be treated by using
benzoyl peroxide washes or cleaners along with a
topical antibiotic containing
clindamycin.
If this is not effective there are a number of other medications but these would require a prescription eg oral antibiotics, topical or oral retinoids
I hope this helps
